An early start for this one Stuart has laid down the Gauntlet riding the Downs link to Shorham. In total this should be over 70 Miles in a day. This would suit cx bikes and of course mountain bikes.
Riders would be advised to pack a bit of extra food and fluids to keep the energy levels up. There may even be a chance of an ice cream and lunch on the beach.
Although this is not the most testing terrain the mileage will offer a satisfying achievement.
