  • Marathon
  • Half Marathon
  • 50k
  • 20-Mile "Training Run"

Event Details

The Marathon course is USATF-certified and a Boston Marathon qualifier. This will be one of the last races to quality for Boston before its mid-September cutoff date.

Capacity for all 4 events combined is 1,200 runners

All events will take runners on a unique journey on the scenic trails along the South Shore of Lake Michigan. Runners will experience the Oak Leaf Trail and the Seven Bridges Hiking Trail. The course will start and finish at Sheridan Park in Cudahy and also go through four other Milwaukee County Parks: Warnimont Park, Grant Park, Bay View Park and South Shore Park. The majority of the course is on the flat, paved Oak Leaf Trail, but the portions on the hiking trails will be a little more challenging. Still, this is the perfect race for beginning or inexperienced trail runners.

There will be two sections of the course: a 9.5-mile loop to the south from Sheridan Park to Grant Park and back; and a 6.8-mile out-and-back to the north from Sheridan Park to South Shore Park. Runners in all four events will start with the 9.5 loop to the south. Details of each course are as follows:

  • Marathon - 9.5-mile loop to the south, 6.8-mile out-and-back to the north, 9.5-mile loop to the south, plus extra mileage in Sheridan Park to finish.
  • Half Marathon - 9.5-mile loop to the south, 3.6-mile out-and-back to the north.
  • 50k - 9.5-mile loop to the south, 6.8-mile out-and-back to the north, 9.5-mile loop to the south, 5.4-mile out-and-back to the north
  • 20-mile Training Run - 9.5-mile loop to the south, 6.8-mile out-and-back to the north, 3.7-mile out-and-back to the south

All runners will receive a high-quality technical shirt and goody bag, and all finishers will receive a medal.

Course Description

Section 1 – Sheridan Park to Grant Park (5.3 miles). This section includes a small amount of road at the start and then the rest is paved trail until the turnaround around Mile 4.2 in Grant Park. Then it will take Grant Park Drive about 1.1 miles north to the Seven Bridges Trailhead. It is mostly flat but there is a couple of rolling hills. There is an aid station 2 miles from Sheridan Park on the Oak Leaf Trail and another one at the turnaround.

Section 2 – Seven Bridges Hiking Trail to Sheridan Park (4.2 miles). This section is a mixed bag of terrain, with dirt trails, wooden bridges, rocks and even some steps. The trail will veer to the north and will take runners through a grassy section near Grant Park Picnic Area #7 before getting back on the Oak Leaf Trail for a short distance, and then picking up the Forked Astor Hiking Trail in Warnimont Park. There is a maze of paths back there so runners will have to pay close attention to the course markings. Although the Forked Astor is mainly flat, it can be slow due to the many winding paths. The hiking trails come to an end just south of the Cudahy Gun Club and at that point runners will get back on the Oak Leaf Trail and follow that into Sheridan Park, where aid station 3 is located.

Section 3 – Oak Leaf Trail from Sheridan Park to South Shore Beach (6.8 miles, out-and-back). The entire section consists of the paved Oak Leaf Trail and has some rolling hills, but none very steep. Aid station 4 is located about 2 miles south of Sheridan Park, right off Lake Drive in St. Francis. Aid station 5 is another 1.5 miles down the trail at South Shore Beach (the turnaround point).

All participants will cover sections 1 and 2 once. The marathon and 50k runners will traverse those sections twice, and the 20-milers will do part of it a second time. Section 3 will be covered in its entirely by the 50k runners, the marathoners and the 20-milers, while the half marathoners will turn around at aid station 4 and head back to Sheridan Park.

Course Rules and Reminders

  • Pacing from non-registered participants is not allowed.
  • The entire course will be open to the public. Please be mindful of cyclists, strollers, hikers, roller bladers and people walking dogs. If you are coming up from behind them you may want to communicate your presence.
  • Do not throw any garbage on the trails. You could be disqualified if you are seen littering. There will be plenty of trash receptacles near the aid stations.
  • Please do not leave the trails for any reason.
  • There will be medical personnel at every aid station. We will also have volunteers stationed at other points on the course.
  • The course will be marked with signs and arrows. Please pay attention to where you are going.
  • Headphones are allowed but discouraged. You will need to be able to hear at all times due to the potential for cyclists or other runners coming up from behind you.
  • There will be a spot for drop bags in Sheridan Park near the finish line. All participants will pass this spot at least once during the race (marathon runners will pass it twice, and 50k runners three times). You can place anything you’d like in these bags and they will be accessible when you cross this portion of the course.
