Organised by ex orienteer Mile Prosser, its has a fairly amusing daily update and is a one off effort to enter (but you had better get to it quickly). Like the velogames comp, you have budget cap (300 Boardmans).
Once entered you can track yourself against a bunch of mates who are also entered.
I am getting withdrawal symptoms already. Went looking for Vuelta start list rumors last night. I expect an entertaining race as usual and then there is the mountainous worlds to ponder.
