T-shirts

Every registered runner will receive a Clarence DeMar Marathon shirt plus a finisher’s medal when you cross the finish line.

BUT… If you want to guarantee that you’ll get your requested shirt size, register early!!

We do our best to give each runner their size, but to get the really cool shirts we all love, we have to order pretty far in advance. If you register early, then we can make a more accurate order.

Help us help you—register early! And pick up your packet with your amazing t-shirt early!

Refunds

There are NO refunds available.

Requests for deferment can be made to the race committee if done before end of day 9/16/2023 and must be for injury reasons only. If a deferment is granted, the runner’s entry will be deferred for the following year’s Clarence DeMar Marathon.
