What racers and reviewers say
- RaceRavesRaced 2026 · aggregator · Mixed
88 ratings, 3.8 overall; difficulty 3.2, scenery 3.1, production 4.0, swag 3.8. Runners find it a decent but forgettable race: good medal, parking and volunteers, but thin crowds, little Garmin or Oz theming, aid shortages and marking mistakes.
“It was actually a much hillier course than I expected.”
- FindMyMarathonRaced 2025 · aggregator · Mixed
3.2 from five reviews. Mentions a course-marking problem near mile 19 (31 km) in a past year and hills in the back half; stats show 543 finishers in 2026 and a 4 to 7 percent Boston-qualifying share.
- Marathon Training AcademyRaced 2013 · blog · Positive
Called it a well-organized small marathon: hilly first half through neighborhoods, wooded trail out-and-back, 1 °C (34 °F) windy start, plentiful volunteers, easy parking and toilets, small expo and good post-race food. About 700 marathoners.
“a well-organized small marathon”
- BibRaveRaced 2016 · aggregator · Positive
Older reviews describe a heavy Wizard of Oz theme, amazing spectators in those years, a small expo and good medals; some find it flatter than expected, others hilly with a tough final 3 km (2 mi). Parking traffic on a two-lane road and storm delays reported. Course changed in 2016.
