04 The format

What is a time trial?

A time trial is a set distance run flat out, against the clock. There's no pack to sit in and no finish-line sprint for position. Your time is your result, and the only person you're racing is you.

The trick is pacing. Go out too hard and the back half falls apart. Most people run their best time trial by starting a touch slower than feels right and finishing fast.

A short time trial, like a mile or 3km, is one of the simplest ways to measure your running fitness. Run it again a few weeks later and the clock tells you exactly how far you've come.

Mile
1,609 metres, or 1.61km. The classic distance for a flat-out run.
Even pacing
Running each part of the distance at the same speed, the fastest way to a good time.
Negative split
Running the second half faster than the first.

FAQ

The Clock the 3 challenge, explained.

A 3km time trial in the Harry's app, run from Thursday 14 May 2026 to Friday 14 August 2026. You ran 3km (1.9 miles) outdoors as fast as you could, and your time decided how many entries you got in the prize draw.
It depends on your age and how much you run, but here's a yardstick. Australia's average parkrun 5km is about 33 minutes, walkers included, which works out to roughly 20 minutes for 3km at the same pace. Clock the 3 rated 15 to 20 minutes as 'Solid', 10 to 15 as 'Competitive' and under 10 as 'Elite', and as of October 2026 the world records are 7:17.55 for men (Norway's Jakob Ingebrigtsen, 2024) and 8:06.11 for women (China's Wang Junxia, 1993).
Elite, under 10:00, earned 50 draw entries. Competitive, 10:01 to 14:59, earned 30. Solid, 15:00 to 19:59, earned 15. In the Fight, 20:00 and over, earned 5.
The fastest man and the fastest woman on the leaderboard each won a $250 Harry's merch pack. A COROS watch and a King of the Hill ticket went to a random draw from all valid entries, weighted by tier.
Yes. Only one attempt counted at a time, but you could resubmit to improve. Your latest run replaced your previous one.
No. It was outdoor running only, tracked on a GPS wearable, and the activity had to show 3.00km or more.
Clock the 3 was a members challenge, so you needed a Harry's membership to enter. The app itself is free to download.
No. Harry's challenges are virtual, so you do them wherever you are and log them in the app.
