For 70 mpw is 14 double 5’milers equivalent to 7 ten milers

Most people will believe singles are better because you’re running for a longer time getting your mileage in at one effort. But you have to dig a little deeper than that.

Doing doubles allows for you to run more quality paces and also work on running with better form and not run sloppy. If you’re gonna run 10 Miles in singles, by the 8-9th mile you’re less focused on form and running quality.

Also, I believe time between running is longer doing singles which sound better for recovery, but you really don’t need much recovery if you’re just doing base mileage. It’s probably better to more frequently get your heart rate up(doubles).

I would say ultimately if you’re out of shape and trying to get in great shape. Do doubles no doubt. And you begin doing specific pace work for Say a pre-competition phase, then you go to singles for your recovery days and double on your workout days with either a short 3-4 mile shakeout(if your workout is in the afternoon) or a 30-45 min cross training session(if workout is in the morning)

Basically,

Running 7-10 mile runs at 7:00 per mile

Vs.

Running 14-5 mile runs at 6:30 per mile

That’s a big difference in my opinion and I believe the person doing the doubles will be a lot fitter than The person doing the singles.

But even with that said I believe the person doing the doubles should have 1-2 days out the week where they single. Wed and sun would be good

M- 5/5

T- 5/5

W- 10

Thur- 5/5

Fri - 5(quicker)

Sat- 5/5

Sun- 15

This may be a good model for someone looking to get in great shape. Alternating strides and hill sprints after each 5 miler

yes, many pro runners do doubles, but they do them while running over 90- 100 mpw. Running 130 a week in doubles is completely different than running 70 a week in doubles.

Seb Coe never did more than 70 now & he did doubles.

Another note for marathon runners it's easier to get up to 70 on singles as the long run takes up more if it.

For track runners doing more shorter interval sessions and w shortest long run it would be hard to do 70 now on singles and your end up doing too many long plodding runs

14x5 = 70

7x10 =. 70

So 14x5 is equal to 7x10.

If I run 70 mpw in doubles I run 14 times per week vs 7 in singles. The guy running singles gains something from the longer workout length but not enough to make up for only doing half the sessions that I'm doing. Frequency of running matters. All things being equal the doubler will outperform the singler.

Isn't that myth rejected by now?

Yeah. Coe doubled but also ran a lot of mileage. Like most pros. Isn’t too surprising.

Henry Marsh doubled at 40 or so.
