Bonking – and how to avoid it (Freewheeling France)

What is bonking?

This term 'bonking' refers to extreme fatigue that’s triggered by hitting the wall or the ‘bonk’.

It's a condition that hits even the best cyclists at one time or another – Chris Froome was famously penalised during 2013 Tour de France after Richie Porte picked up some energy gels for him inside the last 5km of Alpe d'Huez. Risking a penalty was worth 'avoiding the bonk'...
