2:10 half marathon pace chart (6:10/km, 9:55/mile)
To finish in 2:10, hold 6:10 per kilometre (9.7 km/h) from the start line to the finish. On even pace you pass halfway in 1:05:00. Below: every split, a negative-split option, what the goal implies over other distances, and the paces to train at.

Splits
Every checkpoint, two ways to run it
The even column holds 6:10/km all the way. The negative-split column runs the first half 1% slower (6:13/km) and the second half 1% faster (6:06/km): 1:05:39 at halfway, then 1:04:21 for the way home. The gap is small on purpose. One per cent costs nothing early, keeps some glycogen for the last kilometres, and stops you from banking time you will pay back with interest.

What 2:10 is worth over other distances
Peter Riegel's formula (T2 = T1 × (D2 / D1)^1.06) turns one race time into another. Read it the other way round: if your latest 10K is well slower than 58:55, the goal is ambitious for this season.
| Race | Time | Pace |
|---|---|---|
| 5K | 28:16 | 5:39/km |
| 10K | 58:55 | 5:54/km |
| Half marathonGoal | 2:10:00 | 6:10/km |
| Marathon | 4:31:02 | 6:25/km |
The marathon side of these figures assumes marathon-specific training: long runs past 30 km and enough weekly volume. Without it, most runners finish slower than Riegel predicts. Run your own time through the race predictor
Training paces
The paces a 2:10 goal asks for in training
Jack Daniels sums up a performance in one number, VDOT. This goal works out at VDOT 33.2, and his tables derive five intensities from it. They are the paces of the runner you are training to become: if your races are slower today, train at today's paces and move them as you improve.
Easy
8:05–6:47/km
Most of the week. You can hold a conversation.
Marathon
6:20/km
Steady blocks inside long runs.
Threshold
5:55/km
Comfortably hard: 20 minutes in one go, or 5 × 6' with short rests.
Interval
5:27/km
Reps of 3 to 5 minutes, close to VO2max.
Repetition
5:08/km
Short and fast, 200 to 400 m, full recovery.

Key session
3 × 3 km at 6:10/km, 1 km easy between
The session that tells you whether 2:10 is realistic. Run it four to two weeks before race day. If the third rep feels like you could run a fourth, the goal holds. If you are hanging on from the second, a slightly slower goal will give you a better race.

The volume and frequency are a coaching rule of thumb, drawn from how training plans for this kind of goal are usually built, not a statistic and not a requirement. A runner with years of running behind them reaches the same time on less; someone new to the distance often needs the top of the range.

6:10 per kilometre, which is 9:55 per mile or 9.7 km/h. Held evenly, it brings you home in 2:10. Courses are measured on the shortest line, so your watch will probably read a few hundred metres more: aim a couple of seconds per kilometre faster than the chart.
About 58:55 for the 10K, or 28:16 for the 5K, by Riegel's formula. Over the half marathon the prediction is usually close, as long as your weekly volume lets you hold a hard effort for twice as long.
Either works as long as the gap stays small. Even pace puts you through halfway in 1:05:00. The negative-split version passes in 1:05:39 and runs the second half in 1:04:21. Starting faster than the chart rarely pays: the seconds banked early come back, with interest, at the end.
Put 2:10 on your watch, not on a wristband.
