Thinning the Herd

Run as far as you can each week. Every Sunday the bottom 25% were eliminated, and whoever survived three cuts went head to head in a Grand Final week.

01 How it worked

Run more. Or go home.

For three weeks you logged as many kilometres as you could, Monday to Sunday. At the Sunday cutoff the bottom 25% were eliminated, and everyone who survived went into that week's prize draw.

Week 4 was the Grand Final: everyone still standing went head to head, and the most kilometres that week won. There was no minimum distance and no need to run every day, as long as you stayed out of the bottom 25%.

04 The format

What is a last one standing challenge?

A last one standing challenge is an elimination. Everyone starts together, the target keeps getting harder or the slowest get cut, and you stay in for as long as you keep meeting it. The winner is the last person still going.

It comes in two common shapes. A rising target, where the distance grows every day or every lap until nobody can keep up. Or a regular cut, where the bottom of the field is knocked out at a set time, every week, until only a few are left.

That makes it a different kind of hard. Speed barely matters. Recovery, routine and stubbornness do, because the people who win are the ones who still turn up on the days it hurts.

Cut-off
The point where anyone short of the target is out. Miss it once and your challenge is over.
Rising target
A distance that grows as the challenge goes on, so every day is harder than the last.
Last one standing
The only finisher. Everyone else stops somewhere along the way.

FAQ

The Thinning the Herd challenge, explained.

A four-week running elimination in the Harry's app, from Monday 30 March 2026 to Sunday 26 April 2026. You ran as far as you could each week, the bottom 25% were cut every Sunday, and the survivors went head to head in a Grand Final week.
In weeks 1 to 3, your total distance from Monday to Sunday was all that mattered. The bottom 25%, rounded down, were eliminated at 11:59pm AEST Sunday, and the results were announced at 12pm AEST Monday.
No. There was no minimum distance and no need to run daily. You could submit once a day, so if you ran more than once, all those runs went up together in one entry.
Yes. 8:00 per km or faster, based on elapsed time. Slower runs didn't count, and it was outdoor running only, no treadmills.
Most kilometres in Week 4 won. If it was tied, the longest single run in Week 4 decided it, then the fastest average pace.
Four prize packs, one each week, for a $2,279.76 prize pool. Each pack had Altra Experience Flow shoes, a 12-month Harry's app subscription, a Harry's tee and an Altra tee. In weeks 1 to 3 a pack was drawn at random from that week's survivors, and the last one went to the Grand Final winner.
Yes. Thinning the Herd was free to enter with the Harry's app, which is free to download.
No. Harry's challenges are virtual, so you do them wherever you are and log them in the app.
