Ten ways to
be measured.

A set distance, in one run or added up across the window. 5K, 10K, half, full, or a number you choose.

Completed when

One validated run meets or beats the distance inside the window — or, added up, your validated runs reach it together.

Extra requirements

Pace to hold, minimum average heart rate, calories, elevation gain, cadence — on a one-run distance.

Outdoors only

If you want it. A treadmill’s distance is the belt’s estimate.

A set distance against the clock. Completers are numbered fastest first, and everyone who completes gets the same.

Completed when

One validated run covers the distance. Add a finish-under time and the clock becomes the bar.

Typical use

Sub-25 5K. Sub-50 10K. The number you’ve been circling for months.

Note

It needs a GPS wearable: your time comes from the track it recorded.

Run on every day of the challenge. Miss one and the streak is over, which is exactly the pressure people ask for.

Completed when

Every day in the window carries at least one qualifying validated run.

Note

The minimum distance for each day is set when the challenge is created.

Turn up a set number of times. The one for people whose problem isn’t intensity, it’s attendance.

Completed when

You log the required number of validated sessions inside the window, one a day at most.

What counts

A 1 km run or ride, a 400 m swim, or 15 hard minutes in the gym.

Typical use

Four gym sessions. Three swims. Five runs that actually happened.

Kilometres on the bike, in one ride or added up across the window, depending on how the challenge is written.

Completed when

Validated rides reach the target distance.

Extra requirements

Minimum average heart rate, calories, elevation gain.

Lanes or open water, as your wearable recorded them. Metres are metres.

Completed when

One validated swim covers the target distance inside the window.

Extra requirements

Pace to hold, calories.

Note

The wearable must be recording the swim. A length nobody measured never happened.

One session of a set length that has to be genuinely hard, judged on effort rather than distance — useful for training that doesn’t travel anywhere.

Completed when

A validated session of the set length, with your heart rate in an effort zone. No rep counting.

Extra requirements

Minimum average heart rate, peak heart rate, calories.

A step goal across the window: a total, a total with a daily floor, or a target every day. The most democratic challenge on the platform.

Completed when

Your wearable’s step count meets the goal, the way the challenge is written.

Note

Steps count from your wearable only. A phone in your pocket doesn’t count.

Typical use

10,000 a day for five days.

Recovery counts as training. A sleep target measured by the wearable — every night, or on average across the window.

Completed when

Your nights meet the hours you set, every night or on average. A missed night counts as zero.

Note

Requires the wearable overnight, for at least three nights. No wearable, no night.

Minutes at or above a heart-rate zone you set. It doesn’t care what you were doing, only how hard you were working.

Completed when

Validated activities bank the target minutes at or above the zone.

Why it exists

Some of the best training doesn’t show up as distance.
