Looking at the results it looks fairly clear that run was preferable to bike. Could of been very different 3 weeks back when it was all bone dry but we have had 3 wet weeks and I think this slows you more on the biking than the running. I guess not having the kayak also changes it quite a lot.
You're very right. Seven of the top 8 ran first. Nick Dallimore was the only exception but he was sensible in limiting the extent of biking that he did. Great result for Mr Dallimore! Clare and Mark P did well too.
