I've been wanting to do an ultra for years and have made tentative plans for working toward one a few times, but now (having gained permission from my Wife!) is the time to take the plunge and I think Race to the Stones is the one for me (if it's on, as I heard somewhere that Carphone Warehouse are out and they're still after a sponsor.) It's about ten months away so plenty of time for preparation, it looks like decent terrain (not too flat or too hilly) and it's a good, challenging distance.
It probably won't actually be my first Ultra as I would likely do at least a 40 miler during training, but it would definitely be my A race for the year. I've run two marathons in the past year and do a weekly base mileage of around 20 miles, plus around 30 miles on the bike. I won't be able to go huge on the training as I'm quite busy, but I will definitely be giving it a lot of focus. My two marathons became total and utter obsessions leading up to them!
Anyway, does anybody have any thoughts on this race as a choice for a first 100k? I see there's a two day option but my thinking is that I'd be better pushing on and getting the whole thing done as I never sleep well in a tent and that would make starting again the next day seriously difficult.
