I've had two interesting experiences with caffeinated GU's (Cliff Shot Mocha).
- A few weeks ago, hard hilly run. Felt very strong through 9 miles, 4 left. Started feeling a bit weak, then really started thinking about food. Still was able to maintain speed and focus.
Then I ate the GU. Within seconds, I stopped running. Completely shot. Walked nearly a mile then hobbled back the last 3.
- Yesterday, very hard ride. Lots of PRs along the way. Was eating bars, keeping fueled. At 45 miles, ate another of these GUs. Started to feel immediately sluggish. So I ate the other one. Came to a favorite "Strava segment" and could not muster any effort. Struggled through, cross eyed. Limped the last 5 miles home.
What gives? Have any other had similar issues with caffeinated gu? It's obviously time to switch, but I've taken them for years without really noticing this bonk after eating.
