The Importance of a Well Timed Mid-Season Break 08/28/2026

Sometimes the best thing you can do for your fitness is take a break.

If you’ve been racing and training hard all summer, now might be the perfect time for a mid-season reset. Especially if you still have late-season races on the calendar or you’re planning to transition into cyclocross this fall.

A well-timed break doesn’t mean losing all your fitness. Done correctly, it gives your body and mind a chance to recover while preserving the fitness you’ve worked so hard to build.

The key is knowing when to step back, how much recovery you actually need, and how to get training back on track afterward.

The Importance of a Well Timed Mid-Season Break It's believed that the emphasis of a successful training is the intervals, volume and improving FTP. Really, the key is well timed periods of rest.

The True Price of Human vs AI Coaching 08/14/2026

Can AI build you a training plan? Absolutely.

Can it recognize when you're mentally burned out, adjust your season after a disappointing race, calm your nerves before a big event, or help you navigate the highs and lows of being an endurance athlete?

Not quite.

The best coaching has never been about delivering workouts, it's about building relationships. A great coach learns how you respond to training, understands your goals, adapts when life gets in the way, and helps you become a better athlete over the long term.

If you've ever wondered whether AI can replace a coach, this is a conversation worth reading.
