The Suwanee Half Marathon is an annual USATF certified half marathon road running race. It was established in 2015 and has been run every year since. It passes through landmarks such as Suwanee Town Center, Suwanee Creek Greenway and George Pierce Park. The course USATF certification is GA14090WC and is a qualifier for the Peachtree Road Race, the world’s largest 10 km race. Performance Race Services administers the half marathon and the 5K that shortly follows it known as the Old Town 5K.

The Peachtree Road Race is an American 10-kilometer run held annually in Atlanta. After being held on Independence Day from 1970 to 2019, the race was cancelled because of the COVID-19 pandemic after originally being set for Thanksgiving. It is the world's largest 10k race, a title it has held since the late 1970s. The race has become a citywide tradition in which over 70,000 amateur and professional runners try to register for one of the limited 60,000 spots. The event also includes a wheelchair race, which precedes the footrace. In recent years, the race also has a special division for soldiers stationed in the Middle East. The race attracts some of the world's elite 10K runners and has served as both the United States' men's and women's 10K championship.
