Hoping for some advice! My son competes at XC in the 5k range (He’s still at school) Recently he’s been having issues with feeling really sick during afternoon races. I assume it’s related to his food intake and timing and hope he can tweak what he eats to prevent the nausea. To complicate things he has coeliac disease (autoimmune disease to eating gluten), is lactose intolerant and suffers from oesophagitis. He can’t eat oats because of this and eggs also make him sick - aaaaaaaaargh!
The majority of his competitive runs are at around 11 am so he will normally have a bacon bagel and glass of milk at around 8am in the morning and then has a pretty good race, no sickness.
His county races are mainly in the afternoon between 2-3pm so he has 2 meals beforehand - cereal and milk at around 8/9 then the bacon bagel at around 11. He is finding that after about 1k he starts to feel very sick and underperforms as a result. He is adamant that he is very comfortable with his pace and not going too fast.
He has always had to eat around 2.5/3 hours before running – any closer to the run and he has reflux. He did try skipping lunch once and that was a disaster. He can whizz around a 9am park run without eating breakfast with no problems though!
Any advice would be greatly appreciated as he is getting very disheartened. He has ADHD amongst other issues and running is the thing that makes him feel good about himself.
