Marathon Analysis

One thing that has been nagging me is my performance in London Marathon and two weeks later in the Marafun.

During training I was consistently running 18 miles in about 3hours. My best time was 2.54 in February. I was also feeling pretty good (but tired) after 18 miles. Based on these times I should easy be able to do a marathon in  about 4hr 20mins.

So why did I run London in 5.30 and Marafun two weeks later 4.56?

When I have a look at the results my average pace in training is 10 mins per mile. At London it all started to go wrong at mile 15 when I started to feel sick ( I am sure it was the gels and the heat) and at Marafun it all started to go wrong at mile16 when I go cramp in my calf, which I think is because I still had London Marathon in my legs from two weeks prior.

I just know I can do a Marathon in sun 4.30

My next Marathon is Beachy so that will be interesting!
