About this race
The Oldest Race in the State of Indiana and the Flagship Race of our club - Indy Runners and Walkers! Initiated in 1970 by educators and coaches from Carmel High School, and managed by our volunteer led, not-for-profit club since the early 80's, Sam Costa has the legacy, charm, and friendly participant experience you would expect from a race put on by runners for runners. The Half is a test of early season fitness for those who train all winter. The Quarter provides a distance to build on for those with aspirations for longer events later in the Spring. Either way, the Sam Costa has a place for you! There is a 3-hour time limit for the Costa. This equates to a 13:44 pace for the Half Marathon (27:28 for the Quarter). Walkers are strongly encouraged to select the Quarter Marathon.
The Sam Costa is brought to you by Indy Runners and Walkers, Indiana's largest RRCA-affiliated running and walking club. All net proceeds from the race benefit the Indianapolis running and walking community by providing high school scholarships, the healthy promotion of walking and running as a lifestyle activity and competitive sport, seasonal training programs, community runs/walks, and so much more.
Special thanks to our hosts at Northview Church in Carmel, the Costa venue since 2006, for their hospitality and for providing a warm indoor space in their Student Activity Center for pre-race and post-race activities.
