A train halted runners on the course for several minutes in 2016, which was obviously a disaster for many. It did not impact me as a middle of the pack runner, however. I think the race director/ organizers could have done a better job of responding to the issue after the fact.
Flat, rail trail course. Prepare for warn temperatures. After party was nice.
Easy to get to start, mostly on trail, easy to park near finish
A train crossing did stop the race but apparently that was the first time it's happened.

Because this marathon is "the last call" in trying to BQ for the following year, they get a high percentage of qualifiers. I ran it twice and had a much faster time at Philly which is 10 weeks later. My two friends who ran Philly and Via also had a faster time at Philly.
A good part of the race is run on crushed stone. I think it takes more effort than running on roads.
