Your longest ride (on a MTB)?

100 miles all off road as part of a Lincolnshire police fitness challenge some years ago. Last 30 in the pouring rain, that was character building.

I've just recalled my final day (last year) of the transpennie trail which we followed religiously... it wasn't on mountain bikes, but on off-road touring bikes that had camping kit, stoves, autumn weight sleeping bags (so basically winter weight)... It was 128km or 80 miles and mostly off-road. That was really hard work despite it being the last day of a 2 week touring holiday and us being exceptionally fit by then. It was up and over the Pennies with around 90-100km off road. We started at 6:30am and got home 13 hrs later!

Longest ride in 1 day without stopping (apart from a wee break) was the Leeds Liverpool canal last year, 132miles* West to East in 9hrs 29mins

Plus several miles to and from the end of the route as well.

I ride sections of the Canal but at the Leeds end. I do plan to explore more of it, but not that sort of distance for a longtime! fantastic effort
