Free. You can start with nothing.
MuleSkinner's 50 Miler starts at 5:00 AM, before dawn, and has a 14-hour cutoff, starting and finishing at Tinicum Park on the Delaware Canal towpath. Entry requires at least two marathon-or-longer finishes, within their cutoff times, in the past two years. Headlamps are recommended for the early miles, and 50 Milers may carry a drop bag.
MuleSkinner runs the Delaware Canal towpath along the Delaware River in Bucks County, Pennsylvania, with a half marathon, marathon, 50K and 50 miler all starting and finishing at Tinicum Park. The towpath is flat, fast and non-technical, and the race is built as a generous-cutoff, welcoming first trail ultra rather than a mountain test. Aid stations come roughly every 6 to 7 miles with water, fruit, cookies, pretzels, Gatorade and soda, and it's a cup-free race, so bring your own bottle or cup. A portion of every entry supports the Delaware and Lehigh National Heritage Corridor, which helps keep the towpath in shape.
MuleSkinner began in 2019. The 2021 edition did not run. It has been held every October since, and 2026 is its 7th running.

These are other people's work and we link straight to them. Watching costs nothing and needs no account. More of them: every race we hold, on film.
Nobody sees it until we have read it. No account, no sign-in.
This changes nothing on the page on its own. Somebody checks it against the race first.
Somebody watches it before it goes anywhere near this page. What we are after is footage of this course, on the ground. If it would be just as true of any other race, it is not this.
We want the address of the file the race publishes, not the file. We download it from there so the page can say where the line came from.
We read every one of these and we write back. Every fact here carries the source it came from, and the way a wrong one gets fixed is a person checking it against what you tell us.
Cutoffs move, races get postponed, lotteries open and close. We read the race's own sources and record where every fact came from. Put your email in and we will send you what changed, and where we read it.
No account, and nothing to cancel.
What happens to your email. Nothing else. I do not sell it, and I will not send you anything except this race changing. One click gets you out.
I keep this catalog because the information is scattered and hard to trust. Telling you when it moves is the same job.
