Winter Nuts is the toughest challenge I've taken on. I had to pull out after 2 of my 4 laps due to my core temp dropping whilst refuelling. Think carefully about clothing options and taking supporters to act as a pit crew between laps. Not just physically demanding but mentally too having to repeat the same lap
The first lap was OK, some tough bits but got through it. The second lap dragged, cold was kicking in things were getting harder. The third lap was one foot in front of the other all the way around just hoping for the finish line.
Having said all that, it was a great day out, the marshals and organisers did a really good job and I'm really glad to have done it and count it as one of the big achievements of the year. If you want to push your boundaries, here is a good place to do it.
