How Can I Support Epilepsy Ottawa During Race Weekend?
Registration for 2026 in now closed. Check back for up to date details later this year.
Sign Up for the Green Bib option when selecting your race (every race has this option)! This means you won’t receive a metal at the end but the cost will be donated back to Epilepsy Ottawa! Be sure to select Epilepsy Ottawa as your charity of choice while registering!
Whether you are running, walking or cheering from a distance, you can create a fundraising page to directly support the work we’re doing at Epilepsy Ottawa. You can do that here.
