Lead time in harness racing is the time from the start until the leader reaches the start of the final mile, the point 1,609 m from the finish. It exists only in races longer than a mile: in a 2,125 m race it covers the first 2,125 - 1,609 = 516 m, and the four quarters of the last mile follow it.
It measures how hard the field went early, so it belongs beside the draw and gate speed in any read of a race. It is also one of the timing figures used in harness racing betting.
Where lead time is recorded
Harness Racing Australia's (HRA's) results pages print a lead time for each race over a mile, beside its four quarters. The parts add up to the race time. Race 1 at Penrith on 1 October 2026, over 2,125 m:
race time = 38.0 + 30.4 + 30.3 + 29.2 + 29.0 = 156.9 seconds, or 2:36.9
Harness Racing NSW's sectional reports print it as LeadTime (0.00 s for a mile race), and its GPS sheets give each runner its own. HRA form lines leave it out; work it out by turning the mile rate back into the race time (adding the winner's handicap to the distance in a standing start) and subtracting the quarters, as harness racing sectional times shows.
Lead time and the first quarter
The first quarter printed in harness sectionals is the first quarter of the last mile, not of the race: in that 2,125 m race it began 516 m after the start. So a 30.4 s first quarter after a 38.0 s lead time is a field that has already settled, not a slow beginning. In a 1,609 m race there is no lead time, and the first quarter becomes the early-speed figure.
Fast and slow lead times, and the finish
A fast lead time usually means horses fought for the front, spending energy they will want later; a slow one means the leader got there without pressure and can set the tempo. Race 6 at Menangle on 3 October 2026, over 2,300 m, shows the second case. It had a 50.7 s lead time and quarters of 29.5, 29.1, 26.7 and 26.9 s, so a last half of 26.7 + 26.9 = 53.6 s. The horse that led all the way from barrier 1 won by 4.1 m.
In Harness Racing Australia's results for TAB meetings from 1 July to 30 September 2026, 22 track and distance pairs had 40 or more mobile-start races with a lead time. Splitting each pair at its middle lead time, the horse leading at the bell won 336 of 818 races run faster (41.1%) and 406 of 899 run slower (45.2%). Some tracks went the other way, so treat it as a lean, not a rule.
Comparing lead times across tracks
The lead section's length depends on the race distance, and every track has its own set distances. Converting to speed helps, but only so far:
| Race (Harness Racing NSW reports) | Lead section | Lead time | Average speed |
|---|---|---|---|
| Penrith, 1 October 2026, race 4, 1,720 m | 1,720 - 1,609 = 111 m | 7.3 s | 111 / 7.3 = 15.2 m a second |
| Bathurst, 30 September 2026, race 7, 1,730 m | 121 m | 8.0 s | 15.1 m a second |
| Penrith, 1 October 2026, race 1, 2,125 m | 516 m | 38.0 s | 13.6 m a second |
| Menangle, 3 October 2026, race 2, 2,300 m | 691 m | 49.2 s | 14.0 m a second |
Short lead sections come out faster because a short one is mostly the dash off the mobile, while a long one also takes in the settling period after it. So compare a lead time only with others at the same track, distance and start type, since a standing start adds the time to get going from a standstill. A harness racing speed map forecast of who pushes forward is, in effect, a forecast of the lead time.
Lead time, the map and the market
B337 does not forecast tempo or rate runners; it shows prices. The Terminal's racing board lists harness races beside thoroughbreds and greyhounds, with exchange back and lay prices, flucs and a countdown to the jump. Prices are read on a repeating cycle, so check yours with your bookmaker before you bet. Bookmaker names are trade marks of their owners. B337 is not affiliated with them.
Risk: Betting involves risk. A lead-time read is a lean based on past races, leaders win and lose after fast and slow starts alike, and there is no guarantee of profit. See responsible gambling for limits and support.
