On the 9th July 2015, Roger Davies and Sam Wakeling will attempt to break the world record for the fastest 100 miles on a unicycle.

The record currently stands at 6 hours, 44 minutes, 22 seconds and has stood since 1987! Sam and Roger's attempt will take place at Croft race circuit near Darlington. The pair will have to complete 89 laps of the circuit to hit 100m. They will be riding the track in opposite directions to avoid drafting.

The attempt also aims to raise money and awareness for the charity, Water Aid. Their target is to raise £500 but with only two days to go they are still have 35% of that target to raise. If you'd like to sponsor Sam and Roger head over to their Just Giving page.

Both riders are very experienced unicyclists and already hold the world record for unicycling from Land's End to John O'Groats in 6d 8:43, achieved in 2009. Sam also holds world records for the longest distance in 24 hours (453km) and the longest ride without a dismount (105 miles).

Sam will be riding Kris Holm 36″ unicycle with Schlumpf gearbox and 145 cranks. Roger will ride a Nimbus Oracle 36″ unicycle with 89 cranks.

Firetoys wishes both Sam and Roger the best of luck and we'll update the rest of you with the result very soon...
