steady run 7:00:00 
Jura , Brenet to sur le mont de Verriers ( v posh hotel!). Looooong way, started with an extra 3km warm up on roads (Swiss trains not as clear as they could be...) then lots of tracks and bits of tarmac, plenty of hills but nothing too long or too steep. Quite a lot of route had snow cover but nothing more than 4-5cm so skiing would have been a disaster! Snow made things a bit harder than clear tracks and that coupled with a rucksack made things harder than they should have been.
Had right adductor problems from about half way and had to slow significantly but managed it. Longest run for many years!
