Following my participation in the Cambridge Boundary Run marathon for an entry fee of a mere £8, I have decided to calculate the kilometric cost, ie. the entry fee per kilometre, of some of the races I completed in the past. All entries fees are for 2012, unless not available yet for late autumn races, in which case 2011 fees are used. EUR to GBP rate: 0.835.

It therefore appears that I ran successively my most expensive and cheapest (kilometric-wise) races one after each other :) It also seems that the UTMB and the PTL are not so expensive after all...

But what really dominates these tables is no news: "big city marathons" are expensive, as illustrated in this graph by the anomaly at 42.195km. A result of marathons being fashionable, and market laws doing the rest?

It would be interesting to see what are the statistics on a wider scale, though. For example if runnersworld would be keen on opening up their database...
