Alamo City Electrathon

What is the ACE Race?

The mission of the Alamo City Electrathon (ACE) is to foster and encourage partnerships between educational institutions and industry partners. The ACE Invitational was created as an academic opportunity for student programs in high school and community colleges.  Our vision is to generate excitement and awareness of vocational opportunities associated with Science, Technology, Engineering, and Math, by offering students in our region a real-world, hands-on learning experience like no other, we are bringing STEM home to the future workforce of America.

The Alamo City Electrathon (ACE) Invitational was started in 2017 with 6 high school teams participating. By 2019 ACE doubled in participation welcoming from across the region including Boerne, Lytle, Northside ISD, San Antonio College, and St Phillip’s College. In 2021 SoTx was pleased to host ACE at the Alamodome with 20 registered teams from across the nation.


Team Registration Information

Electrathon is a combination of the words Electric and Marathon. Electrathon is a one-hour endurance event for single passenger electric powered cars using no more than 73lb of lead acid batteries.

The Alamo City Electrathon (ACE Race) is a National Sanctioned Electrathon Event with Electrathon America, one of twelve in the nation. This event is exclusive to students enrolled in academic institutions with a STEM/CTE curriculum. Teams are required to abide by the rules and regulations in the Electrathon America Handbook and ACE addendum.

Teams will go through a series of electrical, mechanical, driver, and dynamic inspections the Friday before race day. On race day teams will participate in two one-hour races, the team with the most laps combined from the two races wins.  ACE Race will take place on April 21-22, 2023, at the Freeman Expo Hall.

School’s are required to register student participants per team. Teams must be composed of at least 10 students grade 9th-12th and an Academic Advisor. We encourage teams to establish their own “booster” fundraising bank accounts to avoid delays associated with government procurement spending processes.
