Yes think you should def get some rest. I preferred the first half actually. Was not fond of the ground in the second half with all the stones on the ground.
Well done everyone - I reckon that was reasonably tough coures and much hotter than advertised! Good to meet lots of new faces while running - friendly lot trail runners
Great to meet Jindalee too - thanks for making the effort to say hello 
Same time next year anyone?!
Actually, I've got the small matter of the Salisbury 54321 50k in August but's probably another thread!
Great learning curve for a first marathon though. The last 9km got me understanding Steve Redgrave's famous quote "if you ever see me getting a boat again you have permission top shoot me!". But 15mins after finishing I wanted to better my time in the next run!!
