How do I check if I'm already registered?
Click the Register button above and look for the Confirm registration link. Or you can log into your Race Roster account, click My Homepage under your profile menu, then select the Registrations tab to find your 2021 Houston Half & 10K registration if one is already on file.

We expect COVID-19 will no longer be an issue by October.

How do I register if I deferred in 2019?

All deferred participants from 2019 should have received a coupon code by email in February 2020. If you officially deferred last year and did not receive your code by email, please contact us directly at The coupon will reduce the current Houston Half Marathon registration fee to a flat deferral rate of $35.
