What racers and reviewers say
- RaceRavesRaced 2026 · aggregator · Mixed
30 ratings, 3.6 overall; difficulty 2.8, scenery 3.5, production 3.6, swag 3.2. Agreed: hilly first half, scenic parks, a monotonous out-and-back trail, thin crowds and basic aid.
“Second half is pretty but dull.”
- MarathonGuideRaced 2023 · aggregator · Positive
4.3 from 2 reviews. Gorgeous course, hilly first half and flat second; the Riverwalk was not blocked off.
“Hilly first half, flat back half.”
- Mile By Mile blogRaced 2026 · blog · Mixed
Her 10th marathon. Missing mile markers, long toilet lines, crowded start and a tough bridge at mile 25 (km 40). Hot week beforehand, rain at mile 7, headwind at the end. Finish 3:58:49. Would call it an option for spring if you know what to expect.
“Could be a good option for a spring marathon.”
- BibRave reviewsRaced 2019 · aggregator · Mixed
About 20 BibRave reviews. Positives: Brandywine Park, the riverfront start, well-stocked aid and organisation. Negatives: a steep climb after mile 6 (10 km), thin back-half crowds, a rainy slow 2019 and a heat-stroke case.

Rolling hills early, pretty but dull second half, passes a prison twice, little crowd support.
- RachelRuns on RaceRavesRaced 2024 · aggregator · Negative
Disappointed: run-down side streets, a hilly start, a finish area breaking down at about 4.5 hours with no volunteers, a detour near mile 21 (km 34). Would not return.
“Would not return.”
- kalyke on RaceRavesRaced 2024 · aggregator · Mixed
Good emails and quick packet pickup, congested shared start with walkers in the first mile, plenty of water and sports drink, little but cheerful crowd support.
- BrianYowler on RaceRavesRaced 2023 · aggregator · Positive
Thorough pre-race messages, no real expo, a shaded course with a flat bike-trail finish, beers from Dogfish at the end.
- djsumrs on RaceRavesRaced 2025 · aggregator · Mixed
Lively start and finish, hills at miles 6 to 8 (km 10 to 13), secluded nature reserve with no crowd until about mile 25.
