Bronco test
The Bronco is the repeat-effort benchmark in both rugby codes: five continuous rounds of 20m, 40m and 60m shuttles, no rest, 1,200m in total. It is short enough to be brutal and long enough that pacing decides it.
Sub-5:00 is the Bronco time most club rugby players target, and times under 4:45 are in the range reported for professionals. The test is 1,200m — five continuous rounds of 20m, 40m and 60m shuttles with no rest. Forwards and backs are normally assessed separately.
Pacing is worth more than fitness here: players who go out hard on round one routinely finish 20–40 seconds slower than an evenly paced version of themselves.
The point of the test
Repeat-effort capacity with change of direction under fatigue. It sits in the awkward middle ground between a sprint test and an aerobic test, which is exactly where rugby is played.

How to run it
5 rounds of 20m–40m–60m shuttles, continuous, no rest. Touch the line at every turn. Stop the clock at the end of round 5.
- What you need
- A flat 60m run-up · Cones at 20m, 40m and 60m · A stopwatch
What is a good score?
The honest answer is that the score that matters is your own previous one. But you want a number to sit against, so here is one — with its limits stated.
| Time | Roughly indicates |
|---|---|
| Over 6:00 | A base that has not been built yet. Very common at the start of pre-season. |
| 5:15 – 6:00 | Community and lower-grade range. |
| 4:45 – 5:15 | Strong club to semi-professional range. Sub-5:00 is the number most players are chasing. |
| Under 4:45 | The range reported for professional players, backs typically faster than forwards. |
What people get wrong
Most of the variation between two tests is protocol, not fitness. These are the faults that make one score incomparable to the last.
- Going out far too hard.
- The single most common error, and the most expensive. The first round should feel controlled and slightly frustrating. Players who blow the first round routinely finish 20–40 seconds slower than an evenly paced version of themselves.
- Rounding the turns.
- A turn is a deceleration and a re-acceleration, and it is where the test does its damage. Rounding them makes the score faster and the test meaningless — and it is the reason two clubs' Bronco times often cannot be compared.
- Not touching the line.
- Same problem. Hand or foot on the line, every turn, every round.
- Treating it purely as a fitness test.
- It is also a change-of-direction test. If you have never trained deceleration, you will lose time at 25 turns you did not know you were losing.
How to actually move the number
Three things move a Bronco time, in this order of return:
1. Pacing. Before you train anything, run it evenly. Split your target by five and hold it. Most players find twenty seconds here without getting fitter.
2. The aerobic base. The Bronco is 4–6 minutes of near-maximal work, which puts it squarely in the range where aerobic capacity is the limiter. Easy volume and threshold work raise the ceiling.
3. Repeat-effort intervals with turns in them. Straight-line intervals do not prepare you for 25 decelerations. Shuttle-based intervals do.
Train Smart's Bronco plan sets a target time, works out the week's working pace, and builds the three-session week around it — one quality day at target pace, one threshold day, one endurance day — retesting every four weeks.
