After 23 years, we know that running is in our DNA, and since we are still striving to be our best selves, we all need time to nurture our bodies and souls. We have the perfect race for you. The 23rd annual Simsonian 5K Kick-Off Classic will again offer both an in-person and virtual race option for all to enjoy. The Grosse Ile “tradition” and traditional in-person race will be held Saturday, August 16, 2025, at Grosse Ile High School 7800 Grays Drive on beautiful Grosse Ile, Michigan. The One Mile (1) Fun Run/Walk begins at 8:30 a.m. with the 5K race starting at 9:00 a.m. The course is a fast, flat course with views of the Detroit River and natural areas, with a finish on the track of the refurbished Grosse Ile High School stadium. Runners receive a coveted T-shirt, DJ’d after-race party, refreshments, and great raffle prizes (must be present to win). For those who cannot join us in-person, the Friends of Sims are offering the wildly popular alternative –the Virtual Race experience, with the window of competition from August 1, 2025 to August 16, 2025. You can use your GPS to map your 5K and run, walk, or crawl your own race, at your own place, at your own pace. You just enter your final time on August 16, and you’re all set. If you are not able to participate in the live or virtual events, please consider clicking the “Donate” button and help support this most worthy cause. The 23rd Annual Simsonian is held in memory of beloved teacher and coach, Steve Sims, who died unexpectedly of a dissecting aortic aneurysm in 2003 at age 47. All proceeds from the races, virtual or live, go to the Grosse Ile Educational Foundation Steve Sims Leadership scholarships given to an outstanding male and female scholar/athlete at GIHS. To date, more than $60,000 have been awarded throughout race history. So, your participation and support go to advance the spirit and legacy of Steve Sims in paying it forward to another generation of promising youth--just what the Grosse Ile Educational Foundation, Inc. has done for almost 30 years.
