Biker attempts to beat London marathon record... in traffic

AS BRITISH favourite Mo Farah prepares to challenge the British record at the London Marathon this weekend, an enterprising biker has decided to try it himself – in the thick of London traffic. On closed roads a man vs machine race would be a bit one-sided, but with the average speed of a fast marathon runner being 12.43mph and the average speed of a motorbike in London traffic being 12.5mph, the result turned out not to be so clear-cut – the biker missing out on the record by a full five minutes. Using the same BMW F800GS Adventure as is loaned to the marathon organisers, Michael Mann of online community Bike Social followed the route as closely as possible, albeit with a few extra loops where the runners will take advantage of closed one-way streets.
