📩 Check your inbox!
Flat Branch Ultra runners who have already registered—an optional premium hoodie add-on has been sent to your email.

A few people are already claiming theirs, so don't miss out if you'd like one!

⏰ Please act soon. Because registration is already open and this option is being added after the fact, we're not going to manually track hoodie orders all the way up to race day.

If you've already registered and want a premium hoodie, please take care of it within the next 48 hours. After that, the hoodie option will no longer be available for existing registrants through this manual process.

Moving forward, anyone who registers for the Flat Branch Ultra will be able to add a hoodie automatically during registration on UltraSignup.

Thank you! We appreciate your prompt response. We simply wanted to make sure nobody who had already registered missed out on the opportunity to order a premium hoodie if they wanted one.

See you at Flat Branch!
