This event is quite simply.......AWESOME, Done it twice now, The first one we where breaking through the ice to get into the water, Last year wasnt too bad but still a bit "fresh"
As Gareth says try and pull away from the crowds, This will help you keep moving and prevent standing around at obstacles.
My training was pretty varied to be honest, I had a great route planned where I live, The first 4 miles where a combination of roads and off road terrain, then Id hit a river so as mad as it sounds id jump in and lye there for a few minutes, Then get up and run the remainder. This helped me a little when jumping in and out of water on the course!
Just enjoy it, Its a great day and a great atmosphere.
The next BIG one is the 20 miler this year, 200 obstacles!!!!!!!
