I’ve spent a number of years bouncing back and forth between mountain biking and trail running. A few other people I know have had done the same thing, including my brother.
For certain stretches, I’ve felt like I go months (or even a year) just focused on one, or the other. Other times, I feel like they’re each an equal part of my outdoor recreational life… and that the cross-training helps both pursuits. I’ve also used mountain biking as a way to keep training, with lower impact, while recovering from repetitive running injury (e.g. stress fracture). And, of course there’s the variety. I’ve also sometimes felt like I should just drop one, so I can really focus and make some gains on the other.
So, for anyone bouncing back and forth between trail running and mountain biking, just curious what your experience has been.
