Join Yorkshire's Brain Tumour Charity for our first ever Big Bike Challenge at York Cycle Circuit! This is a 4-hour endurance event where cyclists compete to cycle as many circuits of the 1km track as possible, raising sponsorship for a great cause. You can compete as part of a relay team or as a soloist, and you can cycle for the whole time or just for an hour! Cyclists start at 12pm and their last lap will be at 4pm. YBTC pledges to cover the cost of the cycle circuit; your side of the bargain is to raise a minimum sponsorship of £100 per person.
