Thirlmere Mountain Bike Routes
Thirlmere is a reservoir in the central Lake District national park and it sits nestled between the high mountains of the Helvellyn range to its east, and High Seat and the Wythburn Fells to its west. Wyth Burn feeds the reservoir at its southern end, and Thirlmere empties into St John's Beck to the north.
Mountain biking in the area is perhaps not as extensive as other parts of the Lakes but there are routes and bridleways dotted about, although they may involve some tough hike-a-bike climbs or slow, picky descents. At Dob Gill, to the southern end, a bridleway climbs steeply past Harrop Tarn and then Blea Tarn to cross Watendlath Fell, before descending very steeply to Watendlath Tarn. This takes you over to the west, on the east side at about the same point a steep, stepped bridleway climbs right onto the Helvellyn ridge. This is completely unrideable either up (and most likely down), but is probably the quickest way onto the ridge if you don't mind shouldering the bike and carrying for an hour or so.
Thirlspot, also on the east bank, offers a much more rideable bridleway (in both directions) which also gets you onto the ridge between White Side and Lower Man. Finally there's Sticks Pass which crosses the Helvellyn range from Legburthwaite at the northern end of Thirlmere, passes between Stybarrow Dodd and Raise and eventually descends to Glenridding. This is mostly rideable in both directions, with just a few push/carry sections along the way.

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.
