On 9th October 2011 (9/10/11), Will Duckworth and Darren Mansell ran the Eden Project Marathon. A much harder challenge than was anticipated, Will completed it in 4 hours, 50 minutes and Darren in 5 hours, 12 minutes.

7 years later they're going back to settle the score. And you can ensure they suffer by donating to Acorns and guilting them into working really hard for a good time.

(Darren): "It broke me last time and I took 6 months to recover. I've got unfinished business."
