Are drop bags allowed on the 50 Mile course?

Yes, drop bags are allowed on the 50 Mile course. Runners may provide up to five on course drop bags, and one for the finish area, one per aid station. Drop bags go in at bib pickup Friday evening and Saturday morning. Label each with name, bib number and aid station. A small duffel or dry bag of no more than 10L is ideal. No large duffle bags, garbage bags, paper bags, suitcases, rigid plastic bins, ice chests or coolers, and no perishable items or glass bottles.

Are pacers allowed on the 50 Mile course?

Yes, pacers are allowed on the 50 Mile course. A pacer may join starting at mile 32.8. Pacers may join their runners at Elk Creek, Oxley and Spurgeon only (not Leota).

Pacers are not allowed drop bags.

What is the cutoff time for the 50 Mile course?

The overall time limit for the 50 Mile course is 19 hours from the start. Race cutoffs exist for several reasons, primarily safety, keeping the race on schedule, and out of respect for our volunteer's time.

The course

Where it goes point to point · 9 aid stations

Course line from the race's own GPX. Source file. Recorded 2026.

A point-to-point 50 miler along the Knobstone Trail, Indiana's longest footpath, running north from Deam Lake State Recreation Area to Delaney Creek Park. Runners check in and out at every aid station, and aid stations cannot be skipped.

Steep ascents, technical descents and relentless rolling hills, over rocky ridges, dense hardwood forest and narrow winding paths. Expect exposed ridgelines with sweeping views and shaded valleys with multiple creek crossings. The descents can be slippery in wet conditions.

The race

What this one is

A point-to-point 50 miler along the Knobstone Trail, Indiana's longest footpath, often called "The Little AT" for its steep, hilly landscape. It runs north from Deam Lake State Recreation Area in Borden to Delaney Creek Park in Scottsburg, with steep climbs, ridgeline views and forested valleys. Finishers etch their name on the Finisher Slab, a piece of live edge wood made for each year of the race.

Are you the race director? Get in touch and we'll make it right.

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.

Where this came from. Every fact on this page records its source and when we last checked it: 105 sources for this race. Hover a source link to read the sentence it came from.

37% of what we track for a course is filled in. The rest says "not checked yet" rather than guessing.

Ultras change. We will tell you when this one does.

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.
