Course & elevation
Bayshore is flat and fast, an out-and-back that hugs the shore of Grand Traverse Bay with water in view for nearly the whole way. There are no real hills, just the occasional gentle roll, which makes it one of the Midwest’s most reliable spring PR and Boston-qualifying courses. The lakeside setting is scenic and calming, and the symmetrical layout makes pacing simple, leaving the wind off the bay as the only meaningful variable.

- 600 → 602 ft

- +2 ft
- Total gain
- ≈ 14 ft
The certified route
Out and back along the east shore of Grand Traverse Bay, north from Traverse City on E Shore Rd and Center Rd, then Bluff Rd to the turnaround just past mile 13.
- Start
- On the west side of the east entrance of Cedar Log, 77 ft 3 in from the west edge of the sewer manhole cover and 2 ft 1 in from the east edge of the cement piling of the light fixture.
- Finish
- At the north end of the bleachers.
Underfoot
Essentially fully paved.
Through, in order
Traverse City
What you pass
- Miles 8 to 19: Bluff Rd along the bay
- The turnaround on Bluff Rd near 14705 Bluff Rd, at mile 13.1
- Mile 1: the Huron/Chippewa intersection in Traverse City
Worth knowing
- Runners have the full width of the road from the start to Eastern Ave and E Shore Dr (near mile 2), must stay in the right lane until they return past the same corner (near mile 24), then have the full width again to the finish.

Key moments
- Mile 1–4Out along Grand Traverse Bay, flat and beautiful; hold back and let the field thin.
- Mile 13The turnaround on the out-and-back, a natural checkpoint to assess your effort.
- Mile 18–22The mirror-image return along the bay, where a flat course rewards even pacing.
- Mile 26Back toward the start area for the finish along the shoreline.
Pacing strategy
An even effort is ideal on this flat out-and-back. Note the wind direction on the way out. If it’s at your back early, expect to fight it on the return, so don’t overspend before the turnaround. Stay patient, share the work in packs, and let the back half come to you.
Pacing by goal time
Checkpoint splits for four common goals at Bayshore Marathon. These are effort-even rather than pace-even: the paces shift with the course profile, so climbs are slower and descents faster by the amount the grade actually costs. For any other goal time, use the planner below.
| Checkpoint | Sub-3:00 | Sub-3:30 | Sub-4:00 | Sub-4:30 |
|---|---|---|---|---|
| Mile 3.1 | 20:366:51/mi | 24:027:60/mi | 27:289:08/mi | 30:5410:17/mi |
| Mile 6.2 | 41:126:52/mi | 48:048:01/mi | 54:569:10/mi | 1:01:4810:18/mi |

Splits assume even effort and are adjusted for this course's climbs and descents, which cost more than they give back. A model, not a promise: wind and heat move real splits around. See how the pacing model works.
Plan your mile splits
Turn your goal time into a mile-by-mile plan for Bayshore Marathon, built from this course's elevation. The even pace approach comes pre-selected, and grade-adjusted pacing evens out your effort across the climbs and descents.
Plan Bayshore Marathon splitsFueling & hydration
Aid stations spaced roughly every 2 miles with water and sports drink. With nothing to break your rhythm it’s easy to under-fuel, so keep gels on a fixed schedule, and drink a little more if the bay is warm and sunny on the way back.
Weather
Late-May northern Michigan is usually cool and pleasant for racing, starting in the low-to-mid 40s and warming into the 50s or low-60s, often calm and clear, with bay wind the main variable.
What race morning has actually been like
The last 5 editions of Bayshore Marathon, measured at the start line rather than averaged across the month. Starts have run 42–62°F, averaging 51°F.
| Year | Date | Start | Dew pt | Wind | By late morning |
|---|---|---|---|---|---|
| 2019 | May 25 | 62°F | 65°F | 12 mph | 70°F |
| 2022 | May 28 | 45°F | 47°F | 1 mph | 62°F |
| 2023 | May 27 | 46°F | 42°F | 7 mph | 70°F |
| 2024 | May 25 | 60°F | 59°F | 12 mph | 60°F |
| 2025 | May 24 | 42°F | 43°F | 6 mph | 51°F |
The gap between the gun and late morning matters here. In 2023 it went from 46°F at the start to 70°F by late morning. A four-hour finisher ran a materially different race from a three-hour one.
Dew point has reached 65°F (2019). Above about 60°F, sweat stops evaporating efficiently and most runners lose pace no matter what the thermometer says. It is the number to watch here, not the air temperature.

Is Bayshore Marathon a good Boston qualifier?
Yes. The course actually finishes 2 ft higher than it starts, so no downhill adjustment applies, and nobody can accuse the time of being gravity-assisted.
This drop is our estimate rather than a figure from the course's certificate. If it sits near a threshold, confirm with the organizer.
Compare every course, how the downhill bands work, or work out your own target.
