I too am looking at my first Ultra. I have previously run marathons one of which being the Neolithic Marathon.
I am looking at The Ox (white star running) which is 35 miles and seems to fall on the May bank holiday and I can second The Salisbury 54321 I have done the 30k and aside from the lack of signage around the last bit in the city centre its a good set-up.
I have looked for a similar thread on this subject but can't see it so hoping you could help me out?
I have been using the AdiStar Ride 4 and before that the AdiStar Ride 3 but Adidas have discontinued the line and have superceded them with the Boosts. I am not very keen on the Boosts (really, really narrow) and am wondering if anyone has found a decent replacement?
I like the fact that the Ride's were quite narrow and neutral with a slight cushioning. Alot of the shoes I have found are like running in slippers and I'm a bit out of ideas as there are only so many shoes I can try on.
I eat porridge with a bit of honey about 3-4 hours before and then a narna about 30 minutes before.
The one recommendation I will make is treat your long runs as marathon day training. Eat what you think and see what works for you. Its the only way to know that it won't upset you and what works for you.
