+1 and like you I have concern about it being good enough which is why I have decided to commit. Mind you most races have been paced to a specific time rather than eyeballs out. That way I can continue to get PB's for a few years!
You are right about pacing etc Phil. Although I am using planned paces it is actually fairly comfortable as I am guilty of not really training at what I can do but I'm determined to make a good effort this time. Wenty I have a gap too (and would be bigger if I actually raced properly) but if it works for you don't get too worked up. I think we all adapt plans/paces as we get to know what works best for us as individuals.
I'm in Devon so I'd still have to drive to London, pay car park etc so it's not cheap. Drove up that way last year with family but we stopped a few days in the Lake District each way. Sadly poor planning as wrong date to do Loch Ness My first was 4:43 - so painful I swore I'd not do another.......
You seem to be missing January - May but some good races there - quite fancy Loch Ness but it is a long way from me. I have Thames Trot Feb, The Grizzly March, London (sub 3?), May - Imrys Mara, June Dartmoor Discovery and Endure24. Need to find a nice ultra for the Autumn as the good ones are filling fast!
