The 11th Annual Shamrock Shuffle will be held at Lady Bird Johnson 10700 Nacogdoches Rd, San Antonio, TX 78217.
The run is a relatively flat out and back route on shady paved park trails. This is a jogger/stroller friendly course that is scenic and fast. Dogs will be allowed. We do ask all stroller and dog runners to be courteous to other runners and start near the back of the pack. 

All 5k runners registered by March 3rd will be guaranteed a t-shirt and finishers award. After March 3rd, our available inventory will be represented in registration. If you are able to register for a size, we have it in stock.

Please note, if you do not attend the event, you will only be able to pick up a race shirt on an AS AVAILABLE basis. The shirts left over after the event will be all we have to offer those who do not pick up before the event. 

There are no refunds for the race. Please see our refund policy below:  
To produce an awesome race, we coordinate our efforts and plan well in advance, making it difficult and costly to make changes after registration. Medals, bibs, shirts and other items are ordered months before the race and purchased according to the original information provided during registration. As a result, and similar to other races in the industry, iRun Texas and Split Second Productions does not offer refunds of registration fees for any reason. In addition, release forms and emergency content are specific to the individual participant. Transferring such information would be a liability to the participant as well as the race. This policy applies to individuals with injuries, unexpected business, family emergencies, etc. There are no exceptions.
