I hear this all the time in the community: "I only had 45 minutes so I didn't bother riding." And every time I hear it, I want to shake people by the shoulders. Because 45 minutes is plenty. It's not a consolation prize — it's a proper training session if you use the time well.
Think about what fits into 45 minutes. After a 10-minute warm-up, you've got 30 minutes of working time. That's enough for five solid threshold intervals with recovery between them. It's enough for eight VO2max efforts. It's enough for a sweet spot block that will measurably shift your fitness. You don't need three hours to make progress.
And the maths works in your favour over the course of a week. Four 45-minute sessions is three hours of training. If those sessions are structured and purposeful, they'll outperform two three-hour rides where half the time is zone 1 faffing. The research backs this up — training frequency and intensity are more predictive of fitness gains than raw volume, especially for the time-crunched rider.
The other piece that gets overlooked is adherence. The biggest predictor of whether a training plan works is whether you actually do it. A 45-minute session that fits into your lunch break or before the school run is a session you'll do five times a week. A three-hour epic that requires diary negotiations, childcare arrangements, and weather cooperating? That happens twice a month if you're lucky.
I'm not saying long rides don't matter. They do, especially for endurance events. But if you're in a phase of life where time is tight, stop treating short rides as wasted rides. They're the backbone of realistic, sustainable training. Use them well.
