The Isle of Man is famous for its motorcycling course, but each year amateurs on pushbikes are given the chance to test themselves on the 37.7 mile circuit on September 26.
Riders can choose between one, two or three laps of the island’s Mountain TT Course with the option to ride as part of a relay group.
While it is not a race, riders will be given electronic timing tags, with Chris Boardman holding the record for the fastest ever lap of the Mountain TT Course. The time trial speciallist sped round the island in 1hr, 23m and 54sec, but no-one expects you to beat that time.
Three laps of the route sees you riding 113.2 miles with 6,396 feet of ascent and is apparently the most popular of the three distances.
New for 2015 is a 24hr challenge where riders (individual or as a team) try to complete as many laps of the island as possible in a full day.
Teams can comprise of even numbers from two to 12 people, with entry costing from £180 per rider.
Sign up at the Isle of Man CC sportive website for either of the challenges.
