I ran another 5km race yesterday, ran 50 secs quicker than 2 days earlier. Was wretching 50 metres from home, but stomach pains grew as end approached. I did stretch my strides and increase my pace. Ate 4 hours before and then had half a banana an hour and a half before, water in small supply. Felt better. Maybe more intensive training and knowing my limits.
Ever since I took up running 5k park runs every saturday and the odd 10k, 10 mile races I wretch hard in the last 25% of the race. This is the one thing that is stopping me progressing as my training is going very well, including intervals, hills, easy long runs.
When i run the race I blast out and get sick quicker, yesterday I ran well within myself and felt sick half way into it and wretched hard 1km from home.
I have tried different eating patterns, e.g. 2 hours, 3 hours, 4 hours before the race. No food, some food (porridge or cereal or banana), water, sports drink, tea etc
I am starting to think it may also be psychosomatic.
