IRONSTONE 100K: Legs of Iron. Resolve Like a Stone.

Only ten have survived what we jokingly (but not really) call the Pennsylvania Season of Sufferfest Series. It’s not official. There’s no medal, no plaque, no finish-line hug. Just the quiet acknowledgement that some people willingly stack five of Pennsylvania’s hardest ultramarathons into a single six-month span and come out the other side more or less intact.

To earn entry into this very small, very questionable club, a runner must complete:

• Hyner Trail Challenge 50K — the PA trail racing rite of passage.

• Worlds End Ultramarathon 100K — a wilderness odyssey with no easy miles and no tomorrow.

• Ironstone 100K — 100 kilometers of ridgeline punishment and quartzite reminders of your questionable  life choices.

• Eastern States 100 — the high altar of Pennsylvania suffering circumnavigating the "Wild and Bewildering" River/Course.

• Black Forest 100K — a dark yet epic run through the Reaper’s backyard.

This page exists for one reason: so the efforts of these runners aren’t lost to tall tales told during long runs and half-remembered stories. Their names deserve a place to live—somewhere between legend and a warning to others.
