Recurring Half Marathon races near Ann Arbor

Races that repeat — weekly, monthly or yearly

Spooky Sprint - Toledo
SUN OCT 4
Spooky Sprint - Ann Arbor
SAT OCT 24
Spooky Sprint - Ann Arbor takes place in October at Kensington Metropark, featuring a half marathon, 10K, 5K, untimed 1-mile, kids' dash, and a virtual option. Bodies Race Company presents this event as part of its Holiday Series, designed for runners aiming for a personal best and families seeking a costume-welcoming fall activity. The longer races use chip timing with live results, while the 1-mile and kids' dash offer a relaxed pace. The half marathon begins in the morning, following park roads shaded by trees and paved trails around Maple Beach. The course has a fast, gently rolling terrain, avoiding steep hills. Costumes are welcome, and finishers will receive Halloween treats. Early registrants get race merchandise, including a custom bib, a designer shirt, and a medal. The kids' dash is open to children aged 10 and under, with a free option that does not include merchandise. Youth pricing is available for the 5K and 10K, making the shorter distances more accessible for families.
Michigan Monster Dash
SAT OCT 24
The Michigan Monster Dash is a Halloween-themed run and walk held at Kensington Metropark in Milford, Michigan. The start and finish are located at Maple Beach by Kent Lake. Finish Line Runs, a race group from the Detroit/Ann Arbor area, organizes the event, typically scheduled for late October. Participants can select from a 1k Kids Dash, 5k, 10k, or half marathon. A virtual option is available for each distance, allowing individuals to run from home, a treadmill, or a local path. The in-person course winds through Kensington’s wooded area and is described as relatively flat, emphasizing the Halloween atmosphere over a challenging route. Costumes are highly encouraged, contributing to a family-friendly feel across all events, from the kids’ dash to the longer distances. The race supports Make-A-Wish Michigan, with participant contributions exceeding $8,000 for the charity. Previous race perks have included discount coupons from Dick’s in Novi, chocolate milk from Horizon Organic, and jerky packs from Jack Link’s.
Haunted 5K, 10K, 13.1M & 26.2M at Lansing, MI (43)
SAT OCT 24
The Haunted 5K, 10K, 13.1M & 26.2M is a late-October running event in Lansing, Michigan, offering four distances: 5K, 10K, half marathon, and marathon. All races begin at 9:30 AM. Advance registration is required through RunSignup, as there is no race-day signup available on site. The courses are straightforward out-and-backs. The 5K completes one loop, the 10K completes two, the half marathon completes four, and the marathon completes eight. Packet pickup is available 30 minutes before the start and concludes 10 minutes prior. Participants should anticipate a park vehicle fee upon entry, charged per car, not per person.
Miles 4 Meals
SAT NOV 7
Miles 4 Meals includes a 5K run, a 5K walk, and a Kids 1K Fun Run taking place at Water's Edge Park in Corpus Christi. This is the event's 17th year. The children's race starts first, then the 5K run, and finally the 5K walk occurs in the early evening. The 5K course is certified by USA Track & Field, meaning official times are recorded for rankings and can be submitted afterward. Packet pickup is available at the Coastal Bend Food Bank prior to the event. On race day, pickup is at the park, and an awards ceremony concludes the races.
Turkey Trails- Toledo
SUN NOV 8
Turkey Trails-Toledo is a Thanksgiving morning 5K race and walk held at the Eastern Community YMCA on Pickle Road in Oregon, Ohio, near Toledo. The in-person 5K begins at 9am. Race-day registration and packet pickup are available starting at 7:30am. A virtual option is offered for those who wish to receive the shirt and support the YMCA Scholarship Fund without participating on-site. The course begins and ends at the YMCA, following a quick road route through city streets, with a water station provided. Runners can contend for overall, masters, grand masters, and age-group awards, while the walk remains non-competitive. The event embraces Thanksgiving traditions: the first male and female runners reaching the one-mile mark receive turkeys, costumes are judged in categories such as best turkey look-alike, and the finish area offers fruit, baked goods, sports drink, chip-timed results, and an awards ceremony.
Black Toenail Friday Half Marathon and 7.5 Miler - MI
FRI NOV 27
Black Toenail Friday is a post-Thanksgiving trail race held at Proud Lake Recreation Area in Southeast Michigan. It offers half marathon and 7.5-mile distances, along with virtual and ruck divisions. The race begins at 11:00 AM, allowing participants to sleep in after Thanksgiving. This event is the final race in Trivium Racing’s Michigan Mega Medal Series and typically sells out. The course features well-marked, groomed wooded trails winding through forest and lake sections. The footing is smooth, making it suitable for beginners, yet it retains a distinct trail character compared to road races. The half marathon involves two laps of the course, while the 7.5-mile race completes one lap. Participants aim for personal bests, ruck the course, or run with companions. Post-race activities include campfires, ramen, and hot cocoa. Registration includes a long-sleeve tech shirt, with a hoodie option available.
Turkey Trails- Ann Arbor
SAT NOV 28
Turkey Trails Ann Arbor is an annual Thanksgiving-themed race day in Ann Arbor, Michigan, featuring a half marathon, 10K, 5K, untimed 1 Mile, and Kids Dash. The main races use chip timing with live results, while the shorter family events keep the pressure low. The organizer offers youth pricing for the 5K and 10K, catering to families and runners focused on their times. The exact race location is listed as TBD, with the organizer working with local parks to build courses. The Kids Dash is for children 10 and under, starts just before the main race, and includes a mini bib, youth shirt, and medal. Most registrations include a custom bib, designer shirt, finisher medal, free photos, and finish-line treats, such as free pie. Awards are given to overall, masters, and age-group runners in the 5K, 10K, and half marathon. A virtual option is available for those who want the shirt and medal but cannot attend in Ann Arbor.

SUN NOV 29
Holiday 5K, 10K, 13.1M at Hawk Island Park, Lansing, MI (52)
SAT DEC 26
Winter Trail Fest Half Marathon and 5 Mile - Eastside
SAT FEB 13
Winter Trail Fest East is a February trail race at Island Lake Recreation Area in Brighton, Michigan, offering half marathon and 5-mile options. The objective is to race through whatever winter conditions Michigan presents: snow, ice, slush, or mud. The start is scheduled for later morning, allowing runners and ruckers a bit more daylight and a better chance at milder temperatures before they begin on the trails. The half marathon route follows rolling singletrack, while the 5-mile course provides a shorter, quicker introduction to winter racing for less experienced trail runners. Both distances include run and ruck divisions, a distinctive feature for Michigan winter races that accommodates athletes carrying weighted packs. Finishers receive a WTF hoodie and medal. Racers participating in the Summer Trail Fest Ultra can also collect connecting medals as part of the WTF + STFU Trail Series.
MERCY HEALTH GLASS CITY MARATHON
SAT APR 24
The Mercy Health Glass City Marathon is a spring marathon in Toledo, Ohio, run on a fast, flat 26.2-mile course organized by the Toledo Roadrunners Club. It draws a marathon field of up to 2,000 runners and is built for speed: it regularly ranks among the top 25 fastest marathons, and more than a third of the field runs a Boston Marathon qualifying time. The weekend also offers shorter races, with the Owens Corning Half Marathon, the Savage 5K, and the North Star BlueScope 5-Person Marathon Relay sharing the broader Glass City setup. The marathon and half marathon start on the University of Toledo campus and finish inside Glass Bowl Stadium, giving the race a clear college-campus anchor rather than a generic downtown finish. The half marathon covers 13.1 miles with about 3,000 runners, while the Savage 5K starts by the Clock Tower and ends on the stadium field with more than 1,000 finishers. The full marathon’s speed record is not just marketing: the race has produced the fourth-fastest American marathon, the fastest American marathon debut, the fastest marathon run in Ohio, and Olympic Marathon Trials qualifying performances.

About Half Marathon races in Ann Arbor

Ann Arbor Training Notes

Ann Arbor hosts 23 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals build base miles on the Border-to-Border Trail, Gallup Park Loop, Argo/Bandemer Loop, and the University of Michigan Campus & Downtown Ann Arbor. The B2B runs over 35 miles across Washtenaw County, and Gallup Park gives one full loop at about 3 miles. Bird Hills Nature Area, County Farm Park, Lillie Park, and Leslie Nature Center keep recovery days soft, wooded, and winding. Ann Arbor Running Company anchors the week with Monday 5K, Tuesday intervals, Thursday 5K, and Saturday long runs. Ann Arbor Track Club, PR Run Club, Ann Arbor Runners, Ann-Hua Runners, Bandit Racing Team, Fleet Feet, Michigan AA Next Level Running Club, and Tree Town Trail Runners keep the calendar full. Dexter-Ann Arbor Run and The Big House 5K feel like anchor events.

Locals ride a little gravel, a little tarmac, a little multi-use path, and even some singletrack. Ann Arbor Bicycle Touring Society and Ann Arbor Velo Club give the road scene a real club spine. AABTS ThNR runs 6 km with 211 m. AAVC ThNR runs 7 km with 436 m and turns 63 km into fast rotations, breakaways, chases, and 5 designated sprints. The Dirt Hammer starts at Barton Nature Area, and the Nacho Ride goes about 50 miles west of town. Stein Road brings the hills, and plenty of routes add punchy climbs.

Spring and Autumn are the cleanest months for stacking Z2, intervals, long runs, gravel days, and cyclocross legs. Summer brings warm to hot humid days, with average highs around 27°C and the heaviest precipitation of the year. Locals still run early, use the Huron River paths, and keep Gallup Park or the B2B in the mix. Winter changes the kit first, because average highs sit around -1°C and snowfall averages 91 cm per season. Roads are often plowed, bike lanes do not get cleared, and studded tires are easy to find when ice shows up. Runners shift to Broadway Winter Route energy and use roads when it is dark.
