Every challenge type you can run on Pledro

A Pledro challenge is a target, a window and an entry fee. What changes between them is what is being measured and how long you have. This is the full list.

The ten types

Each one asks something different of your wearable, so the type you pick and the wearable you own are connected. Which wearables can back which type is its own guide.

Distance race — cover a set distance inside the window. The classic: 10km this weekend, a half marathon this month.

Time trial — cover a set distance under a set time. The bar is the clock, so a 5km in under 25 minutes either happened or it did not.

Run streak — run on a set number of consecutive days. Consistency rather than volume, and the type most likely to have you outside at 10pm on day six.

Weekly frequency — a set number of sessions inside the week, whatever they are. The widest type, and the right one when the goal is turning up rather than any particular distance.

Cycle distance — the same idea as a distance race, on a bike.

Swim distance — distance in the water. Heart rate is not used here: optical heart rate underwater is unreliable, and requiring something a wearable cannot measure honestly would fail genuine swims.

Effort session — a session that reaches and holds a real working heart rate. This is the type that cannot be faked by standing in a gym, because the heart rate is the target rather than corroboration of it.

Step count — a step total across the window. Steps count only from a wearable that is worn; a phone in a pocket counts nothing.

Sleep quality — sleep, measured. The one challenge where completing means doing less rather than more.

Heart-rate-zone minutes — minutes spent above a heart-rate threshold. It needs a minute-by-minute trace, which is the narrowest requirement on the platform.

The four formats

The format decides the shape of the window rather than what is measured.

• Custom — you set the start and the end.
• Quick — exactly 24 or 48 hours. For when the intention will not survive a week of thinking about it.
• This weekend — opens and closes across the weekend.
• When full — waits until every place is taken, then starts everybody together 24 hours later.

Whichever you pick, a challenge starts at least 24 hours after it is created. That gap is not a delay, it is the rule that stops anybody building a challenge around a run they have already done.

Public, private, or ours

Public challenges are listed in the hub and anybody can enter. Private challenges are invite-only: you choose who is in it, and nobody else sees it. Pledro official challenges are the ones we run.

There is no friends-only middle tier. Private means invisible, not blurred.

Where the public ones live

The hub sorts open challenges into rooms rather than one endless list, so you can browse by what you are in the mood for: Pledro official, Big funds, Quick ones, This weekend, Grind Coins only, Starting soon, Filling up and For charity.

The ones you are already in sit along the top of that hub, above the rooms, so what you owe yourself is the first thing you see and the browsing comes second.

The rules that apply to all of them

Whatever type you pick, these do not change:

• Only activities inside the window, from a wearable connected before you entered, on a session that began after you entered, can count.
• Nothing counts until the wearable verifies it.
• Everyone who completes is rewarded the same, first or last.
• Complete and your entry comes back in full; do not complete and it stays in the reward fund.
• Every finished challenge produces a receipt carrying a challenge ID.

Can I leave one?

While you are the only person in it, yes — withdraw whenever, no reason needed, entry back in full. Once somebody else has entered, everybody is committed, including you, and completing the target is the only route back to your entry.

If you created it, you can call it off only while you are still the only one in it. After that you leave like anybody else and the challenge carries on without you.
