We've set up a special Facebook group especially for our unstoppable triathletes. Here, we'll give you all the tops tips for your triathlon and you can share your story about why you're taking part to help beat blood cancer. There are offers for kit in our online shop and we'll be holding exclusive Q&A sessions in the coming months to help you prepare for your triathlon.
You can also share your triathlon experiences - whether you're a pro triathlete or a total novice, we want to hear from you!
So join today to become part of our unstoppable triathlete community.
