Race Bag Pickup

All participants who register online via before the April 21st deadline are guaranteed a t-shirt and race bag at race bag pickup, if they ordered one.

Race bag pickup will be at the community center at Keswick Park: 3496 Keswick Dr, Chamblee, GA 30341. Race back pick-up hours are from noon to 9 pm on Friday, April 24th.

Race Bag Pickup will also be available the morning of the race, from 7 am until the race starts at 8:30 am.

If you find yourself unable to participate in the race, please feel free to pick up your bag to claim your race t-shirt, bag, and other giveaways. Any unclaimed items will be forfeited after the close of the event at 10 am.

You may have a friend or neighbor pick up your race bag for you.

Walk-Up Registrations

This event will cap at 1,500 participants. If space allows, we will accept walk-up registrations on April 24th at the Murphey Candler Park Earth Day celebrationĀ and on the morning of the race, April 25th on a limited basis between 7 am – 8 am. The cost for walk-up registration is $40, cash or credit card only.

Please note that walk-up registrants Friday and Saturday are NOT guaranteed a race shirt and bag, and may not receive a timing device. These will be available as supplies last on race day. Walk-up registrants may visit the registration table after the race to claim any leftover shirts and bags. For this reason, we highly recommend registering online before the April 21st deadline!


No one will be allowed to participate without having checked the box to sign our waivers during the registration process. Parents/guardiansĀ must sign waivers on behalf of underage children and anyone else they register. Registrants who sign up offline will be required to sign a paper waiver. Please note that our waivers include a photo/video release, so pictures of your child(ren) may be used in promotion materials, on social media, in local media news, etc. Waiver for Chamblee Fun Mud Run

Cancellations, Refunds and Transfers

Please note that the registration system allows registrations to be cancelled for about 15 minutes after the transaction is processed. After that time, we are unable to process any refunds. We also highly discourage participants to transfer, buy and sell race registrations, or give registrations to each other outside of the registration system. This means that people are participating who are not in our system and have not signed a waiver. This is a safety and liability issue. If you find you are unable to participate for any reason after you’ve registered, please consider your registration a donation to the CMS Education Foundation. You can still claim your race t shirt, bag and giveaways at Race Bag Pickup!
