Your race, on one page.

Goal time, splits, a pace band for your wrist and a gel plan. Free, no account.

Your goal time

Know your goal? Type it in. Not sure? Estimate it from a recent race.

Estimate it from a recent race

Race Your time (h:mm:ss or mm:ss)

Tap an estimate to use it as your goal. Use a race from the last 4 to 8 weeks, on a flat course in normal weather. The Riegel formula assumes equal training for both distances.

Step 2

Weather check

Add the forecast temperature and dew point for your start time. Humid air slows you more than heat alone.

Temperature (°C) Dew point (°C)

Step 3

Gel plan

Choose how many grams of carbohydrate per hour your stomach handled in training.

Carbs per hour Carbs per gel (g, see the label)

Step 4

Your pace band

Every split

Print at 100 percent (actual size). The band is 22.5 cm (8.9 in) long and wraps around your wrist. Estimates and general information, not medical advice: test everything in training.
