BT - thanks, I've added you to the list of entrants for North West Counties.
Paul Rushworth - I would rather concentrate on road ultras really but they seem to be quite thin on the ground in this country from what I can tell. I did the National 100k in Gravesend back in May but decided on Bullock again more because it's local than anything. Anyway I certainly don't think I'm the first person to say 'never again' at the finish! Hope you're enjoying Argentina / Chile, the Bullock won't be quite the same without you.
