W6 R2 I did it!
Saw a snake head on the way, which kept me going... a little green one, chopped off from the body... so someone else had found him first..
The first 10 tough, second 10 ok, but went a bit fast at the end so nearly exploded... Got the gremlins about the jump to 25 minutes solid.. but i did 20 last week and felt good, so... just gotta sort some good music to keep me goin.
