In reply to AndyM-LVB:
Im off there on Tuesday, have been bouldering 2 or 3 times a week (hard sessions, at my limit anyway) for past few weeks but now Ive tapered it down to a couple of easy sessions (indoor routes included for some endurance, as circuits are quite demanding)
Try to get in as much top out practice as you can, this is quite important as you can be as strong and technical as you like but often the hard bit I found was actually getting out of the problem, many a failed effort due to my weakness here on my first visit, if you cant find suitable rock for this do sets of dips to strengthen the 'mantle muscles'.I guess good mantle technique would be more efficient, I usually just grunt and 'whale out' though.
Lots of press ups to keep 'font elbow' at bay.
Yes, sloper practice is good but there are also hundreds of high quality crimpy lines in Font aswell so dont stop training this grip altogether.
Skin - Dont do the dishes at night during your trip, or if you are inclined, wear marigolds.It helps, seriously.I also used Climb On, applying it after every session and loads on before bed time, I think it really helped as my burning tips felt brand new by the morning and I managed 6 days straight with no issues.
Have fun
