In reply to bentley's biceps:
The Fellsman is an amazing challenge, the route that just keeps on giving (hills!) I've done many many events but the Fellsman has a real special atmosphere unlike any other. Remember it started as a walk and is officially still a walkers event thoufgh over the years the number of runners has massively increased. I did my first Fellsman six years ago, I've completed it four times in all sorts of weather.
On a warmer (I'm saying warmer not warm remember) year the boags are unpredictable and deep. You can never tell whether the peat you are about to stand on will give way to ankle, knee or as has been said up to your waist! I've had to be pulled out of a waist deep bog once in the freezing cold of night. Boy was I really glad of the 'grouping' system they have in place then!
If you've done LL100 in 39 hours you'll likely be towards the back of the field but don't let that dishearten you, it's a fabulous event whever you place in the results. I'm gutted I can't make it this year because of other commitments but I highly urge you to give it a try!
