I not sure how long to ride for. I go on long rides about 22 km and Im quite tired after, mainly exhausted riding last leg of journey home. I dont eat much before riding( as its usually too early to want food and its under two hours), should I eat during or is it a endurance thing?
I have mentioned I have a chronic illness, but this is during GOOD days when Im well.
I have only been riding once a week 20 km and up rides for a month.
