So, what's 'The Lap'? And how can you help?

Well, it's a gruelling, yet stunning (I'm told) 47 mile [75 km] trail ultra marathon around Lake Windermere, featuring 2,500m of ascent. Participants - including me! - have 24 hours to complete the circuit, or retire. My training has recently included Grafham Water (14km, ascent 95m), the Boston [Lincs.] marathon (26 miles, ascent 8m (yes, 8)) and Huntingdon ultra marathon (30 miles, ascent 166m), so this is more than a step up. I've done the training, but I'm still pretty nervous!

But my self-inflicted ordeal will be nothing compared to what some children experience in their lives. I would be delighted if you would support me by making a contribution to Embrace, a national charity that works with law enforcement agencies and safeguarding professionals to support children, young people and families who are victims of serious crime.

Please give what you can - whether it's £4.70, £47 or, for any recent lottery winners out there, something bigger. Your money will make a big difference to their work.
