If you see a a big group of mobility scooters on the Mountain Road today don't be surprised: It's the Isle of Nan TT.
Alternative adventure specialists Extreme Trifle are attempting to set a record for the slowest lap of the TT course.
With a top-speed of 8mph they won't be challenging for the ?10,000 prize for the first 100mph lap on an electric powered bike but they are hoping to raise fund for the Joey Dunlop foundation.
Extreme Trifle member Paul 'Oz' Osbourne says today will be their biggest challenge as they climb over the Mountain.
On Saturday they managed to get as far as the Sulby Glen Hotel, having started at the Joey Dunlop House in Braddan.
