The challenge is from the 1 October to the 31 October, or however long it takes you from the 1 October to complete your 42.2 kilometres.
But you can of course start fundraising as soon as you want to!
We are encouraging people to take part in MyMarathon in October as there will lots of tips and support on-hand and you’ll also be eligible for the fundraising prize incentives.
If you are not able to complete it in October then we are happy for you to do your 42.2 kilometres in a diﬀerent month, as long as you sign-up and fundraise. You could also try and run more than 42.2 kilometres if you like!
