Take on one of the South Coast Run Series Challenges for Cancer Research UK and help us to beat cancer sooner.

Taking place on the same weekend as the South Coast Triathlon this run series has three distances for you to choose from. What's more, each race takes place in and around the town of Seaford in East Sussex, so you can enjoy some scenic views of the seafront.

Choose from the half marathon, 10K or 5K, get your sponsorship pack and help us bring forward the day when all cancers are cured.

Join CRUK right now and we'll get you to the finish line. We've got training and fundraising advice to prepare you for the big day, cheering packs for your friends and family, and a dedicated team ready to answer any last minute questions.
