and how do I avoid it? I’ve never suffered from it before, however went out on the roadie again today to explore my new surroundings in the Welsh Valleys and just coming up to a climb, not an especially big one just an incline, spinning quite merrily, no extra effort really, I got an incredible ‘stitch’ which had me bend double and nearly made me stop, managed to ride through it, but it got me wondering what is it, what caused it and more importantly how do I combat/avoid it? I was fully hydrated and fuelled, using my usual drink/foods so no dietary change, and the weather was a combination of cool wind and slight rain but nothing extreme. Cheers all in advance for any hints or tips.
