These are even splits. Most runners are better off a touch slower than this for the first portion, then holding or edging down. Going out faster than goal pace is the most common way this time slips away.

What this goal takes

A 3:30 marathon is a strong recreational goal and a common Boston-adjacent target for many runners. It tends to want 55 to 85 km a week, long runs around 28 to 32 km, and weekly threshold work. The training paces below come from a VDOT of about 44.6.

Hold something close to even pace, or start a few seconds per km on the conservative side. The marathon punishes an aggressive first half harder than almost any other race. Fuel early and often, before you feel you need it.

Common questions

Is a 3:30 marathon a good goal?

It depends on your current fitness and training history. Check a recent race in the VDOT calculator to see whether this pace lines up with where you are now, then give yourself a training block long enough to close the gap.

How many km per week do I need?

See the section above. As a rule, the faster the goal, the more weekly volume and the longer the long runs it asks for. Consistency over months matters more than any single big week.

What pace is a 3:30 marathon?

It is 4:59 per kilometre, or 8:01 per mile, held for the whole marathon.
