You can expect a few aches and twinges in the first few days after the event. Kickstart your recovery by tucking into a nutritious meal packed with protein and carbohydrates. Ease off training for the following week, sticking to gentle spinning or swimming sessions to loosen your muscles. After months of hard training, your body deserves some rest and recovery.
