For fun / adrenalin / relaxation all at once. Messing around on or with bikes is always fun. I love the rush of riding fast singletrack and at the same time being out there is a great stress relief after a bad day/week – in fact the way this week is going I need a ride to avoid going on a killing spree.
Also I used to play football, which was nice but sometimes you didn’t win, same with snooker. Have always been into fishing great for getting out there again but again sometimes there were no fish. With mountain biking on the other hand – the hill is always there to ride up and back down again – it’s a win every time!
