Good training for Iceland.
Yes, must try to throw a few longer runs in like this where I can. The only problem is if it aggravates my knee... :( To be honest I am not quite sure what made it worse recently.
Are you guys going to Iceland? it has great running/hiking and no trees to spoil the view. ( or salal to spoil the running )
WOW! It looks hard! Carrying all that stuff over the lava in that area will be a great challenge but I would love to do it.
