Our second Helvellyn route (the first is here) takes a slightly different approach. We tried to consider which of the many bridleways on the ridge are actually the most ridable, and this is what we came up with.
This route starts one the Thirlmere side of the Helvellyn range, from the car park at Thirlspot. We climb from here on an old pony track onto the ridge, a lot of which is surprisingly rideable. After a quick there-and-back of the summit (ok then, maybe not quick!), the route follows the whole ridge from south to north before descending from Great Dodd on grassy singletrack. Finally, a blast along the Old Coach Road and a short road section gets you back to the car.
