Challenge 100

Complete 100 miles in 100 days and raise £100 to help the 1 in 100 people living with epilepsy.

Runners with medals

Challenge 100 is Epilepsy Society’s brand new virtual challenge for 2021.

Challenge 100 2021 took place between 1 January 2021 and 10 April 2021. There was only one rule with this challenge: you must complete at least 100 miles in less than 100 days; how you completed it was up to you!

Thank you

Thank you everyone who signed up and took part in Challenge 100 2021. Every single one of you, inspired and overwhelmed us with your passion and commitment by walking, running or cycling at least 100 miles in less than 100 days.

Why we need your support

1 in 100 people in the UK are living with epilepsy, and a third of those have seizures that cannot be controlled by medication. 

In the first few months after the start of pandemic our fundraising income dropped by over 50%. Now more than ever we need your support to keep our research projects and support services going for those who need them most.

Every £5 you raise over the target could help distribute tailored information abut epilepsy, ensuring the first five leaflets are free to better seizure control.
