Why you don’t need to do a long run every weekend
Research suggests you can stop cramming your training cycle into one week
The weekly long run is basically running culture at this point, but it probably doesn’t need to be. Performance coach and author Steve Magness recently summed it up on X: “You don’t have to do a long run every week. Long runs are great. But you don’t have to marry them.” Here’s why you should consider spacing those huge efforts further apart.
You don’t have to do a long run every week
Arthur Lydiard popularized the weekly long run as a way to maintain aerobic adaptation, as they were doing 3-5 hard speed/interval sessions a week. The long run was a counterbalance

Your calendar isn’t a training plan
A seven-day “training week” is a human invention, not necessarily based on physiological need. It’s useful for work schedules, but can be less useful (and unnecessary) for your body, which doesn’t care what day it is, and a growing number of coaches are planning in blocks that are longer than a calendar week. Hanson’s Coaching Services‘ Luke Humphrey notes that a microcycle is usually seven days, but “can be 10 to 14 days,” and says Hanson’s Brooks Distance Project uses a 10-day microcycle with a long run every 10th day. (A microcycle is just a short training block—the smallest unit in your plan—with a specific goal for how much work you’re trying to absorb.)
Recovery weeks make the work stick
Training only works when you recover from it. If you keep piling on hard weeks without a breather, you can tip into the kind of fatigue that is detrimental rather than effective. Research on planned overreaching, published in the journal Frontiers in Sports and Active Living, explains that when high-demand training drags on without enough recovery, athletes can veer towards non-functional overreaching and even overtraining syndrome. A longer cycle can help, simply because it gives you more room to place the harder days, then ease off before you are forced to.
Running resource website Run161 suggests a rhythm that can work for most runners: build the training load for two to three microcycles (anywhere from seven to 14 days), then take a reduced-load cycle so your body can catch up and lock in the gains. If you’ve been slogging through runs that should feel easy, that kind of scheduled active recovery time may be what you’re missing.
What a 14-day cycle looks like
A longer training cycle can simply involve two weeks with different jobs. One weekend gets the “bigger” long run, while the other weekend has a shorter, more comfortable (and safe) version. Your hardest workout can be scheduled when you’re actually set up to do it well, rather than when the calendar bullies you into it.
