How long should the long run be?

How long should the long run be?!?

This is a super hot topic that many feel very passionate about.

For more advanced runners I’ll often have them top out in the 20-22 or 3-hour range. The reason for this is any longer and it’s simply a lot of time on their feet that is likely going beyond the point of diminishing returns. Long runs that are too long take too much out of you and require extra recovery time.

For the average (4:30 marathon) or slower runners, it gets tricky because if they want to run 20 miles for the long run, a very important mileage threshold, it’s getting into the 4-hour run range. Mentally it will likely be worth it to at least his 20+ once during training, but going over 3-hours too often, even for 4-5 hour marathoners, is┬ánot necessary in my opinion.
