This was the fifth in a series of charity trail Marathons along the towpath of the Lea Valley. I have taken part in every one but, sadly in 2009 I failed to finish due to getting lost and running out of time. This year the route was changed so, instead of a point to point including a loop around the Lea Valley Country Park, we ran an out and back along the towpath. At the turn around point we ran through the new Olympic White Water Park added a bit of extra interest to the route. I had planned to run all the way with a chum, Kaz, with a view to trying to get under 5-30 but it was not to be. Yet again I was jog/walking from half way and we crossed the line together in 6-15-20, not quite last place! Thanks to Kaz for staying with me to the bitter end.
