Sometimes these things happen. You can hit the Wall in a marathon and still be in fantastic shape. Many factors don’t beat yourself up. I have sort of bonked riding but I have hit the Wall in a marathon, that is not nice. Lucky for me is was in last mile of marathon. I finished fine but could not stand up for 25 minutes after the race. Someone gave me a real coke not diet, I was a completely different person in 10 minutes. Got up and could move fine.
