Assumption of risk

Not medical or safety advice. Plans, paces, fueling, turnaround times, tide or current estimates, and trip estimates are general calculations from the information you enter, and they may be wrong. Exercise, endurance events, hiking, cycling, paddling, and time outdoors carry a risk of serious injury or death. Consult a physician before beginning a training program, especially if you are pregnant, injured, or have a health condition. Check official weather, trail, park, tide, and water conditions, carry the safety gear the trip requires, and turn back when conditions require it. You participate at your own risk. Fueling suggestions are not nutritional advice for allergies or medical conditions.

Replace

Replace the shoe when the miles run out, or sooner

The defaults here are 400 miles for a daily trainer, 300 for a tempo or interval shoe, 350 for a trail shoe, and 500 for a recovery shoe. Those are planning numbers, not a promise the foam is fine until then. A torn outsole, a crease through the midsole, or a new ache in that pair means retire it now.

If a daily shoe has 200 miles left and this week puts 18 miles on it, the date is 12 weeks out. A shoe that is already at the target is due today.

One date is free. $5 shows the date for every shoe in the rotation.

Mileage tracker · Rotation plan

Shoes estimates retire dates by repeating the week you typed. It is not a wear inspection. Retire a shoe earlier for a torn outsole, a flat midsole, or a pain that showed up with that pair.
