Day 262 - Glentress Forest
A fabulous ride in www.glentressforest.com/" rel="nofollow Glentress Forest with Andy and Chris who I met in Luchon in August. We did parts of the www.youtube.com/watch?v=CLaTqoq9Qus" rel="nofollow black route , the red route and the blue route. The only reason I didn't return black, red and blue is entirely due to their great guiding skills on trails they know really well. ( They're part of the team that build and maintain them there) Thanks for a great day guys! PS: I am shorter than both of them but I slipped back down the bank as the timer was running. Honest..
