Where does 8:35/mi come from?

The arithmetic

3:45:00 = 225 minutes

225.00 min ÷ 26.219 mi = 8.582 min per mile

225.00 min ÷ 42.195 km = 5.332 min per km

3:45 marathon = 8:35/mi = 5:20/km, every split of the way

Is a 3:45:00 marathon realistic?

The fitness that makes 3:45 realistic is roughly a 1:45–1:47 half marathon or a 49-minute 10K. Runners coming from a 4:00+ marathon usually find 3:45 responds to one structured build cycle — more long-run volume and a few marathon-pace sessions — rather than a transformation. The risk at this level is going out at 3:30 pace and discovering it at 28 km.

Typical prerequisite performances — rules of thumb, not predictions

5K ≈ 23:11
10K ≈ 47:52
Half ≈ 1:46:15

What does this goal mean for training?

Goal pace is 8:35/mi, with easy days at 10:05–10:35/mi and tempo work near 8:10–8:20/mi. The defining session is the long run with 6–10 miles at 8:35/mi on tired legs; if those feel controlled, the goal is honest.

Training paces implied by a 3:45:00 marathon.
Session	Pace /mi	Role
Race goal	8:35	the pace on the day
Tempo / threshold	8:10–8:20	comfortably hard, 20–40 min
Long run	9:05–9:35	the backbone of the build
Easy running	10:05–10:35	conversational, most miles

Ranges are standard coaching rules of thumb — individual economy varies
