Good luck to all those running the London Marathon today. I still harbour ambitions to do one more marathon, but for the moment I will remain on the side of the road encouraging support. Not a big trading market but it can throw up the unexpected. In 2005 you could have backed the women’s runner in running at 1.50 at 22 miles while firmly in the lead thanks to an unusual situation. It’s worth laying low or backing high when you have sports that are difficult to model. Athletics is one of the sports.
Once again, good luck to anybody running today!
