NDW100 2014 Race Report

1 month, 2 weeks ago (Saturday 16:05, Aug 16, 2014)

It wasn't meant to be that way, as my previous two attempts came and went, so my race plans got scrapped in place of coming back and giving it another go. I knew I could get it right, albeit I would need to run at the upper levels of my ability all day to make it under 24hrs. I looked at those first two attempts as two ideal recce's, albeit 2 efforts in the 20hr range within…
