Learnings from Kipchoge's 2:00:25 feat: 1 Spend time on your recovery. Switch off. Relax. 2 Eat lots of nitrate-rich foods, such as beetroot, spinach, rocket and lettuce. 3 Consume plenty of carbohydrates during long runs. 4 Caffeine taken before and at the end of a race can deliver an energy boost. 5 Go fast when you go long in training. Build up slowly but let loose towards the end.
