Hit a wall (not a real one) cycling today - what happened?
At about 2 hours today, I hit a complete wall cycling. Could barely go more than a mile slowly without needing to stop for 5mins, with my chest hurting and my heart pounding. Last 4 miles took 40mins with the stops.
Background,
I had a reasonably big breakfast (Strada) about 8am. I started riding at 11am, stopped at about an hour for 5mins and had a small breakfast bar, and then at about an hour 45mins in, I just hit this wall physically.
Other info, ride nearly all flat on bike paths. Weather was hotter than normal for me (90F), but I was drinking (water) throughout.
Background, I'm not particularly fit, but I've been getting better over the last 2 years, and this was the worst I've been by far.
So what happened. My wife think it may have been electrolytes. I'm thinking more Carbs. Heat may have played a role. Is this the wall marathon runners get? Something else?
I know I definitely don't want it to happen again, because it was no fun at all.
