Ratings & Reviews for the Seneca Creek Greenway Trail Marathon

1 Stars from 1 Reviews

review of 2015 Seneca Creek Greenway Trail Marathon.   

1 / 5 Stars


In 2014, missing aid station at a critical point. Another aid station ran out of water. No hot food at the end as promised. Just junk food. In 2015, race was postponed to a date pulled out of thin air (not originally offered as a possible date) and that conflicted with a better race nearby (HAT). So a lot of people gave up on Seneca and did HAT which they had already registered for. RD lacks communication skills. Race page is missing critical information or is too vague to be useful; Comments/questions posted to Facebook page are censored.

Race Tips

Wait until the last possible moment to register. It didn't fill up in 2015 so there's no reason to register early. Due to weather and possibility of cancellation, it only makes sense to wait.
