You signed up for a course. Train for that course. PR Run is course-specific training for trail and ultrarunners.

Why the course, not the distance?

A hundred on rolling dirt is not a hundred on a ridge at 10,000 feet. Mileage is a lazy proxy. Vert, grade, heat, and fuel are the work.

The runner who already entered a race. Western States. Hardrock. The hundred in your backyard.

What is a course readiness score?

A course readiness score compares your recent training volume, vertical, climate work, and kit against one specific ultra. It is not a finish time. It is whether this block matches this course.

How is the pr.run Course Readiness Score calculated?

Thirty points for weekly miles and longest run, scaled to the race distance. Thirty for weekly vert against that course's feet per mile. Twenty for the simulations this course actually asks: heat, altitude, night, technical trail, poles. Twenty for kit: shoes, water, layers, fuel.

Is a course readiness score the same as a race time predictor?

No. The race time predictor uses ITRA or UTMB index and last year's winning time. The Course Readiness Score uses your training and kit against Course DNA. One estimates a clock. One estimates whether the work matches the course.

Which ultras can I score?

Any course in the pr.run catalog. Western States, Hardrock, UTMB, Cocodona, Leadville, Badwater, Tor des Geants, and the rest of the twenty-five.

The score this course writes.

Weekly miles, weekly vert, the kit, the simulations this course actually asks. A gear score and a pacing read against Course DNA.

Volume

Miles and the long

Weekly miles and the longest run. This distance has a floor.

Vert

Feet against this course

Weekly gain against this course's density. Quads write the second half.

Kit

What has to hold

Shoes, vest, layers, fuel. The list is short. It still has to be true.
