Where does 7:38/mi come from?

The arithmetic

1:40:00 = 100 minutes

100.00 min ÷ 13.109 mi = 7.628 min per mile

100.00 min ÷ 21.0975 km = 4.740 min per km

1:40 half marathon = 7:38/mi = 4:44/km, every split of the way

Is a 1:40:00 half marathon realistic?

Realistic with a 10K around 45 minutes or a 5K around 21:45. Runners usually arrive here from a 1:45 half, and the 23 seconds per mile between the two comes from regular tempo work and long runs of 10–12 miles rather than from intervals. The pacing trap is the first 5K: 7:38/mi feels comfortable early, and running it at 7:20 is what turns mile 11 into a negotiation.

What does this goal mean for training?

Goal pace is 7:38/mi (4:44/km). Easy running at 9:10–9:40/mi, tempo at 7:20–7:30/mi in blocks of 2–4 miles, and long runs of 10–12 miles with the last 2–3 at goal pace. The −1% band opens at 7:40, brings the last full mile home at 7:36 and passes halfway in 50:08, patient early, strong late.

Training paces implied by a 1:40:00 half marathon.
Session	Pace /mi	Role
Race goal	7:38	the pace on the day
Tempo / threshold	7:18–7:28	comfortably hard, 20–40 min
Long run	8:08–8:38	the backbone of the build
Easy running	9:08–9:38	conversational, most miles

Ranges are standard coaching rules of thumb; individual economy varies.
