Sophie Radcliffe, aka Challenge Sophie is the puppetmaster behind this event. She’s cycled London to Paris in 24 hours numerous times and has led cycling tours supporting and motivating people to achieve this challenge. Her award winning blog helps hundreds of people every year to complete this challenge and inspired her to organise this event.

I created this event because completing it was a life changer for me back in 2008 when I had very little cycling experience. I’ve done it every year since then because I love how empowering it is to cycle between London and Paris in 24 hours. It’s iconic, fun and comes with bags of kudos!

L2P24 will be running for the 6th year in a row in 2020 and promises to be bigger and more awesome than ever.

I would really love you to join us. Cyclists of all abilities are welcome, if you can work up to cycling 100 miles in your training you’ll be in a good place to complete this.
— Sophie Radcliffe, CHALLENGE SOPHIE
