Yes, the Lake Geneva Challenge. A group of cyclists aimed to do a circuit of Lake Geneva and a lone rower was planning on rowing the entire length of the thing.

It was all for charity, of course, and their ridiculous efforts raised over £4000. (Although you can still join in and make a donation….).

And here’s how it happened (there are some links to pictures here but thanks to the magic of technology all the pics are collected at the bottom of this blog):

1. So the Lake Geneva challenge is on… Neil rowing the length of the lake, Gareth biking round it. Here’s the story: http://bit.ly/bSt9G6 #
2. #LakeGenevaChallenge He’s off. Conditions are perfect, water’s like a sheet of glass. Spirits are high. I’m off to MacDonalds. N #

13. #LakeGenevaChallenge The cyclists are about to come back over the border into CH & “il pleut comme une vache qui pisse”. They’re very soggy. #
14. #LakeGenevaChallenge Lake’s choppy & boat wakes are nearly tipping Neil in, so 15 min rest. Happy to hear bikers are stuck in a rainstorm. N #
