Sticking to your marathon training plan but still doubting you can finish? Five weeks out, the novelty of training can start to fade and self-doubt can creep in.
Coach Anya sits down with Carson Gillaspia (@CrustbyCarson) to talk about what this stage of marathon training actually feels like - the honest setbacks, what’s working, and why trusting the work you’ve already done can sometimes be the hardest part.
Known as @CrustbyCarson, Carson’s food and running content has made waves across the internet. He’s spent the last few years championing both the pursuit of the perfect sourdough loaf and long-distance running as tools for mental wellbeing. Now, as he trains for his fourth marathon, he opens up about the doubts that surface as race day gets closer.
As Anya builds towards her own start line in New York, they get into the reality of being five weeks out, how to handle those inevitable wobbles in confidence, and the coaching lessons that can help you trust the foundations you’ve already built.
