The vast majority of women's cycling training works exactly the same way as men's. Periodisation, progressive overload, recovery, fuelling — the principles are identical. The physiology is not a different sport. It is the same sport with a handful of meaningful differences that most training plans completely ignore.
That is the problem. Not that women need a fundamentally different approach to training. But that the specific places where physiology diverges — hormonal fluctuations, iron metabolism, bone density risk, pelvic anatomy, energy availability thresholds — have been systematically under-researched and under-discussed for decades. The science has finally caught up. The cycling world is still catching up.
This is not a "women's version" of a training guide. It is a guide to the specific considerations that female cyclists need to account for on top of the training principles that apply to everyone. Written for capable athletes who happen to have different physiology, not for people who need to be spoken to gently.
The menstrual cycle and training: what actually changes
The internet has made this simultaneously too complicated and too simple. You will find articles telling you to completely restructure your training around your cycle. You will find others telling you it does not matter at all. Both are wrong.
The menstrual cycle creates a shifting hormonal environment across roughly 28 days — though individual variation is enormous, and "roughly 28 days" might be 24 or 35 for you. Oestrogen and progesterone rise and fall in patterns that affect substrate utilisation, thermoregulation, recovery, and perceived exertion. The effects are real. They are also, for most women, smaller than the effect of sleep, stress, fuelling, and training load.
Dr Stacy Sims — the exercise physiologist who has done more than anyone to bring female-specific physiology into sports science — puts it clearly: the menstrual cycle is a variable, not a barrier. You can train in every phase. The question is whether you can train smarter by understanding what each phase does.
Here is what the evidence actually shows. During the follicular phase — from the start of menstruation through to ovulation — oestrogen rises progressively. Higher oestrogen supports glycogen storage, muscle repair, and pain tolerance. Most women report that high-intensity work feels more accessible during this phase. Recovery is typically faster. If you are going to schedule your most demanding interval sessions or testing days, the mid-to-late follicular phase is the strongest window for most women.
During the luteal phase — from ovulation to the start of the next period — progesterone rises and body temperature increases by 0.3 to 0.5 degrees Celsius. This is not trivial. It shifts your thermoregulatory baseline, increases ventilation rate, and can raise perceived exertion for the same absolute power output. Many women notice that sessions feel harder in the late luteal phase. The power is the same; the RPE is higher. This is normal. It is not a sign that you are losing fitness.
Here is where it gets really interesting. A 2020 meta-analysis looking across the menstrual cycle research found that while hormonal fluctuations do affect exercise performance, the magnitude of the effect was small for most measures. The practical takeaway: you do not need to bin your training plan and rebuild it every month. But if you consistently feel terrible during certain phases, tracking your cycle against your training data will tell you whether there is a pattern worth responding to.
The response, when there is one, is practical. Schedule your hardest intervals and key sessions in the follicular phase where possible. During the late luteal phase, be willing to adjust targets by RPE rather than rigid power numbers. Accept that a 5-watt drop in a threshold session during the pre-menstrual days is physiology, not failure. Train through it. Adjust within it. Do not abandon it.
Iron and ferritin: the hidden performance limiter
If there is one blood marker that every female endurance athlete should know by number, it is ferritin. Not haemoglobin — though that matters too. Ferritin. It is your iron storage protein, and it is the early warning system for iron deficiency long before full anaemia develops.
Here is why this matters so much for female cyclists specifically. Menstruation creates a regular iron loss that male athletes simply do not have. Endurance training itself increases iron turnover through foot-strike haemolysis, sweat losses, and increased red blood cell production demands. Combine the two and you have a population — female endurance athletes — that is at substantially higher risk of iron depletion than any other athletic demographic.
The numbers are sobering. Studies consistently report that 15 to 35 per cent of female endurance athletes have ferritin levels below 20 micrograms per litre. At that level, oxygen transport is impaired, recovery is compromised, and performance declines in ways that look like overtraining but are actually nutritional. You feel flat. Sessions that should be manageable feel brutal. You recover slowly. You get ill more often. And because the symptoms overlap with overtraining, many athletes and coaches respond by adjusting training when the actual fix is a blood test and, potentially, supplementation.
The target: most sports medicine practitioners recommend ferritin above 30 micrograms per litre for endurance athletes, with some — including Dr Nicky Keay, whose work on female athlete health has been particularly valuable — suggesting above 50 for women training more than eight hours per week.
The good news is that this is fixable. Get a full blood panel including ferritin at least once a year — ideally twice if you are training consistently. If your ferritin is low, discuss supplementation with a doctor. Iron supplements should not be taken without confirmed deficiency because excess iron has its own health risks. But under medical guidance, supplementation can bring levels back to functional range within 8 to 12 weeks, and the performance improvement is often dramatic. Women who have been running low for months or years sometimes describe the difference as feeling like a new engine.
Dietary iron matters too. Haem iron from red meat is the most bioavailable. Non-haem iron from plant sources is absorbed less efficiently but improves when consumed with vitamin C. Avoid taking iron supplements alongside calcium, coffee, or tea — all of which inhibit absorption.
Bone density: the cycling-specific risk
This one is non-negotiable and it applies to all cyclists, but the risk profile is higher for women. Cycling is non-weight-bearing. Your skeleton gets almost no mechanical loading stimulus from riding a bike. Unlike running, which drives bone adaptation through impact forces, cycling essentially suspends you above the ground for hours at a time. The bones adapt to the loads placed on them. No load, no adaptation.
For premenopausal women, this is a concern. For peri- and postmenopausal women — when declining oestrogen actively accelerates bone loss — it becomes urgent. The combination of a non-weight-bearing primary sport and declining hormonal protection for bone creates a compounding risk that can result in osteopenia or osteoporosis if nothing is done to counteract it.
The research on cyclists specifically is clear. Multiple studies have shown that competitive cyclists — including professionals — have lower bone mineral density than age-matched controls in non-weight-bearing sports. Some studies of professional road cyclists have found bone density values comparable to sedentary populations. The riding itself does not protect your bones.
What does protect them is impact loading. Your bones need mechanical stress — ground reaction forces, compression, impact — to maintain and build density. This means:
Running, even short distances, 2 to 3 times per week. A 15 to 20 minute run provides meaningful bone-loading stimulus. It does not need to be marathon training. It needs to be regular.
Jumping and plyometric work. Skipping rope, box jumps, drop jumps, multi-directional hops. These generate high ground reaction forces in short bursts. Ten minutes of jumping work twice a week is a significant stimulus.
Resistance training with bodyweight and moderate loads. Single-leg exercises — step-ups, lunges, single-leg press — are particularly effective because they load the hip and spine in patterns that are relevant to cycling-specific bone density concerns.
The critical point: this is not something to think about later. Bone density is much easier to maintain than to rebuild. If you are a female cyclist over 35, building impact work into your weekly routine now is one of the highest-return investments you can make for long-term health. This is one area where the evidence is unambiguous and the cost of inaction is high.
Saddle selection: anatomy, not marketing
Here is where the cycling industry has largely failed women. The default approach to women's saddles has been to take a men's design, make it shorter and wider, add more padding, and change the colour to something pastel. This addresses almost none of the actual anatomical differences that affect saddle comfort and performance.
The reality is that pelvic anatomy varies enormously between individuals — both between men and women, and within each group. The meaningful differences are sit-bone width, soft tissue distribution, pelvic tilt under load, and the relationship between the saddle nose and the soft tissue structures of the perineum. Women, on average, have wider sit bones and different soft tissue anatomy in the perineal region. But "on average" hides enormous individual variation.
What matters for saddle selection is not whether the saddle is labelled "women's specific." It is whether the saddle supports your sit bones properly, relieves pressure on soft tissue, and allows you to rotate your pelvis into an efficient riding position without numbness or pain.
The practical approach: get a proper bike fit that includes saddle pressure mapping. This is the single most reliable way to find a saddle that works for your anatomy. Pressure mapping shows exactly where the load is distributed and whether your saddle is creating pressure points in problematic areas. Many women find that a flat or slightly curved saddle with a central cutout works better than a heavily padded one — because excess padding can actually increase soft tissue pressure by conforming around structures rather than supporting the sit bones.
Width matters, but not in the way most marketing suggests. Your sit bones need to be supported on the widest part of the saddle. If the saddle is too narrow, your weight falls on the soft tissue between the sit bones. Too wide and it causes inner-thigh chafing and restricts pedalling mechanics. The right width is the one that matches your measured sit-bone distance plus 20 to 30 millimetres — not a generic "women's width."
Nose shape matters. A shorter, narrower nose with a relief channel or cutout reduces anterior pressure for many women. Some riders do better with a split-nose design. Others find a traditional shape with a deep channel works perfectly. There is no universal answer. There is only the saddle that works for your anatomy on your bike in your position.
If you are experiencing numbness, pain, or soft tissue discomfort, do not accept it as normal. It is not. It is a solvable problem with the right saddle, the right width, the right position, and potentially a small adjustment to saddle tilt or fore-aft position. A competent bike fitter can resolve most saddle issues in a single session.
RED-S: the performance and health conversation
RED-S — Relative Energy Deficiency in Sport — is not an eating disorder. This distinction matters because conflating the two prevents people from recognising it in themselves. RED-S is a state of insufficient energy availability: you are burning more energy than you are consuming, and the deficit is large enough or sustained enough to impair normal physiological function.
The consequences extend far beyond performance. Impaired bone health. Disrupted menstrual function. Compromised immune function. Hormonal dysregulation. Increased injury risk. Mood disturbance. Cardiovascular stress. The IOC consensus statement on RED-S identifies effects across virtually every physiological system. This is not about weight. It is about whether your body has enough fuel to support both training and the basic biological processes that keep you healthy.
For female cyclists specifically, menstrual function is the most visible early indicator. If your periods become irregular, unusually light, or stop altogether — and you are not on hormonal contraception that would explain it — this is a red flag that demands investigation. The absence of menstruation in a premenopausal athlete is not a sign of fitness. It is a sign that the body has downregulated reproductive function because energy availability is too low. The downstream effects include accelerated bone loss, impaired recovery, and increased injury risk.
The warning signs that should prompt a conversation with a sports medicine doctor: missed or irregular periods, recurring stress fractures, persistent fatigue that does not resolve with rest, frequent illness despite adequate training recovery, declining performance despite consistent training, mood changes including irritability and loss of motivation, and food preoccupation that feels different from normal nutritional attention.
The fix is not complicated in principle. It is increasing energy intake to match energy expenditure plus the energy cost of basic physiological function. In practice, this can be difficult because many athletes underestimate how much they need to eat — particularly during high-volume training blocks, and particularly if there has been a gradual drift toward under-fuelling over months or years.
Dr Nicky Keay's framework for assessing energy availability in endurance athletes is practical: total energy intake minus exercise energy expenditure, divided by fat-free mass. If that number is consistently below 30 kilocalories per kilogram of fat-free mass per day, you are in a deficit that will eventually have consequences. The target for health and performance is above 45.
If you suspect RED-S, do not try to self-diagnose. See a sports medicine doctor. This is a medical condition with medical consequences, and the right professional support makes a significant difference in recovery trajectory.
Strength training: what works without the injury risk
Strength training matters for female cyclists for three overlapping reasons: performance, bone density, and injury prevention. The evidence base is clear on all three. What matters is the approach.
For this audience — athletes aged 35 to 55 — the priority is single-leg work, hip stability, and core strength. The exercises that deliver the highest return for female cyclists:
Single-leg work. Step-ups, rear-foot-raised split stance, single-leg press, walking lunges. These build the unilateral strength that cycling actually requires — because pedalling is a single-leg movement pattern. They also expose and correct left-right imbalances that are nearly universal in cyclists. Three sets of 8 to 12 reps per leg, twice per week. Progress the load gradually.
Hip stability. Side-lying clamshells, banded lateral walks, single-leg glute bridges, hip hikes. Weak hip stabilisers are the root cause of a remarkable number of cycling knee injuries. When the glute medius cannot stabilise the pelvis, the knee tracks inward under load, and over thousands of pedal strokes the cumulative stress causes patellofemoral pain. Ten minutes of hip stability work before every ride is both injury prevention and performance investment.
Core. Dead bugs, Pallof press, side planks, bird-dogs. The goal is anti-rotation and anti-extension strength — the ability to hold a stable pelvis and spine while your legs produce force. A strong core transfers more power to the pedals by reducing energy leakage through the trunk. Two to three core exercises, 3 sets each, twice per week.
Impact work. Skipping rope, pogo jumps, box step-ups with a hop, multi-directional bounds. This is primarily for bone density, but it also builds the reactive strength and tendon stiffness that improve pedalling efficiency. Keep volumes modest — 50 to 100 total contacts per session, 2 to 3 times per week.
The strength sessions do not need to be long. A well-structured 30-minute session covering single-leg strength, hip stability, core, and a short impact circuit delivers everything a cyclist needs. The key is consistency — twice per week, year-round, with gradual load progression. This is not periodised powerlifting. It is maintenance and development of the support structures that keep you riding well and riding injury-free.
Perimenopause and menopause: the hormonal shift
This section could be — and is — its own article. The detailed walkthrough is in menopause and cycling performance. What follows is the essential framework.
Perimenopause typically begins in the mid-40s, though it can start earlier. It is characterised by fluctuating and eventually declining levels of oestrogen and progesterone, with symptoms that can include irregular periods, hot flushes, sleep disruption, mood changes, and shifts in body composition. The transition to menopause — defined as 12 consecutive months without a period — typically completes between 45 and 55.
For cyclists, the performance-relevant changes are significant. Declining oestrogen reduces muscle protein synthesis, which means the same training stimulus produces less adaptation. It accelerates bone loss. It shifts body composition toward central adiposity. It impairs sleep quality, which compounds recovery challenges. And it changes thermoregulation, making heat management during hard efforts more difficult.
The training response to these changes is counterintuitive — and this is the part worth paying attention to. The instinct is to back off — ride easier, do less intensity, be gentler with yourself. Dr Stacy Sims argues the opposite, and the evidence supports her. As oestrogen declines, the training stimulus needs to increase in intensity — not volume — to compensate for the reduced anabolic signalling.
Sprint intervals, high-intensity threshold work, and resistance training become more important in perimenopause and menopause, not less. The hormonal environment that previously supported adaptation from moderate training is no longer doing the same work. You need a stronger stimulus to achieve the same response. Sims' prescription: more polarised training with properly hard intervals, resistance work with progressive overload, and reduced time in the moderate-intensity grey zone that produces the least return.
Protein requirements increase. Where 1.6 grams per kilogram of bodyweight per day might have been adequate before, menopausal athletes typically need 1.8 to 2.2 grams per kilogram, spread across 4 meals, with attention to leucine content. The bedtime protein dose — 30 to 40 grams of casein-rich protein before sleep — becomes particularly important given the increased anabolic resistance.
Recovery timelines extend. The 48-hour window between hard sessions that worked at 40 may need to become 72 hours at 50. Sleep — already disrupted by menopausal symptoms for many women — becomes the highest-priority recovery variable. If hot flushes are waking you at 3am, that is not a minor inconvenience. It is a direct impairment to your recovery and adaptation.
HRT — hormone replacement therapy — is a legitimate medical option that some menopausal athletes find transformative for both health and performance. It is also a decision that belongs in a consulting room with a knowledgeable clinician, not in a cycling article. If you are interested in HRT, find a menopause-specialist doctor and have the conversation. The evidence base for HRT in active women is growing, and the old blanket fears about it have been substantially revised by more recent research.
Putting it together: what actually needs to change
The list of things that need to change for female cyclists is shorter than the internet suggests. But the things on it are significant.
Track your cycle — even loosely. You do not need an app that tells you what to eat on day 17. You need enough data to recognise patterns in how you respond to training across the month. Two to three months of tracking cycle phase against RPE and session quality will tell you whether you have a meaningful pattern worth responding to.
Get your blood work done. Ferritin, haemoglobin, vitamin D, and a full thyroid panel, at minimum. Once a year. More often if you are training at high volume or have a history of deficiency. Do not guess. Test.
Build impact work into your week. Running, jumping, plyometrics, resistance training. Two to three sessions, 15 to 30 minutes. This is bone density insurance that you cannot get from the bike.
Strength train consistently. Single-leg work, hip stability, core. Twice per week, 30 minutes. No exceptions, no off-season.
Fuel adequately. If your periods are irregular and you are not on hormonal contraception, that is a signal to assess your energy availability. Not tomorrow. Now.
Get your saddle right. Pressure mapping, proper width measurement, and a fitter who understands female pelvic anatomy. Discomfort is not inevitable. It is solvable.
If you are approaching perimenopause, prepare for the shift. More intensity, more protein, more recovery. The training that worked at 38 will not work the same way at 48. The adjustment is not a retreat. It is a recalibration.
None of this requires a fundamentally different approach to cycling. It requires attention to the places where female physiology creates different demands — and the willingness to address them directly instead of pretending they do not exist or overcorrecting into a completely separate training methodology.
You are a cyclist. These are the refinements. Go and do them this week.
