In reply to thom8822:
There are some lovely rides in this area of varying degrees of difficulty. The first three here are the easiest, then they get harder:
1 Lonscale Loop - head out of Keswick to Threlkeld along disused railway line. Head up bridleway past Blencathra Centre and ride up as far as you can (beck on left). Cross beck, head up for a few hundred metres, turn left, Lonscale Fell is on your right, head back down to Keswick, pick up bridleway down the side of Latrigg. Lots of fun downhill, bit of a short climb at top of beck (push if you want), great fun down the side of Latrigg.
2 Loop of Skiddaw - don't worry, you don't go anywhere near the top! Start as per first route. At the head of the beck turn right. Pass Skiddaw House hostel, follow track past Whitewater Dash, descend to road. Road work back to Keswick.
3 Whinlatter Forest - blue Quercus route is an absolute hoot and very good for beginners. The two red loops are good, too.
4 Bit of a contraversial one - just went up Loadpot Hill from Pooley Bridge at the weekend. Head over Askham Fell to vague direction of Widewath, then onto Keldhead. Pick up bridleway and push / carry to Loadpot Hill (this was a bit hideous). However, from summit of Loadpot it is 5km of easy downhill. Mr Christine thought it was not very technical and lacked finess. I, though, am fundamentally very lazy and thought there was nothing wrong with this. Point bike downhill, keep balance - brilliant! Turn right at bottom of hill for more downhill to Howtown, road back. This is easy riding, EXCEPT for the push up, which might be off-putting. Also nav would be interesting in poor weather.
5 There is a route up to Helvellyn and the Dodds. Head out to Dockray from Glenridding, up to High Row. Climb, climb, climb, ride over top and there are a choice of 3 routes down - Sticks Pass, Keppel Cove or Grisedale (Long). I wasn't a big fan of this, as there was lots of grassy climbing, but each to their own.
6 There is also a loop from Keswick up to Wadentlath, I think it then descends to Rosthwaite, up Honister Pass (not all the way), then pick up bridleway down to Grange via Castle Crag. Bridleway along the bottom of Cat Bells towards Portinscale (!walkers!), return to Keswick - this is quite doable for beginners.
Have fun & hope this helps.
Christine
