Eyup GP. Well I'm certainly no triathlete....unless drowning is one of the disciplines!
But I decided to have a crack at the RoF myself this year. Haven't done anything like it before, & the furthest I've gone so far is 61 miles (the Fellsman this year), so you're looking in the wrong direction for tips from me
However, I believe a top tip is earplugs if you've taken the accommodation option (village hall floor), and also you cross the beach at some point so something to dry your feet / keep them dry to help avoid blisters may be advisable.
But other than that.......haven't a clue other than run till you stop.....then trot till you stop.....then walk till you stop....then it's the crawl till you drop
As cougie says, Oakleys are brilliant, well worth the money so long as you've got it. However, if not and you're after some alternatives, have a look at Sunwise. I paid about £30 for mine and they have intechangable lenses; great for running and biking and no stability issues.
Ah Sam, I didn't realise it was the Hobble you were doing - I did that too...in my Kanadias as there's a fair bit of hard track / tar running. A grand day out, made better by the hotdogs and whisky!! The real bonus was how dry the ground was, I'd run round some of it a few weeks ago and it was a quagmire!
If your Fellrunners are OK for 25 I'd wear them, terrain dependant. I haven't got a pair of those (tried a pair and they felt dammed comfy), but would happily do that sort of distance in my Speedcrosses, even on mixed terrain. The only possible issue is that if there's a lot of hard packed running, the studs will wear down (but i never feel the studs).
Coupled with my Kanadias, the Speedcrosses are possibly the most comfortable thing I've run long distances in.
