Race times that match a 4:45 marathon
By Riegel's formula, a common race-time predictor, a 4:45 marathon is the same effort as these shorter races.
- Half marathon
- 2:16:42
- 10K
- 1:01:57
- 5K
- 29:43
If your recent race times are slower than these, 4:45 is a stretch goal for now. The formula assumes marathon training: a runner with a fast half marathon and short long runs often finishes slower than it predicts. Use the marathon readiness score to check your mileage and long runs against the goal.
Is 4:45 a Boston qualifying time?
A 4:45:00 meets the Boston Marathon qualifying standard for men 80 and older, and for women and non-binary runners 70 and older (2026 and 2027 standards, age on race day). Meeting the standard does not guarantee entry. For the 2027 race, a qualifier needed to be 5:17 under their standard for a guaranteed place; 1,000 more places went by random draw to qualifiers who missed that cutoff.
Who runs 4:45, and what it takes
Finish-line-focused marathoners, including charity-team runners and athletes building up from the half marathon.
At this pace, a runner's fueling and stamina matter more than pacing. A runner finishing between 4:30 and 4:50 usually runs 20 to 30 miles a week, with at least three long runs of 16 miles or more. A runner who walks 10 to 30 seconds at every aid station often finishes faster than one who runs through them. Go through halfway in 2:22:30 and keep the walk breaks regular.
