Double Runs

Pretty well mileage is mileage. Your in a good sweet spot for mileage. Double runs help you get more mileage in and allow you to break up one longer run into two shorter ones making it easier to get it done. If you want more mileage you will have to have a pretty long single run and a shorter one everyday, or add another day.

There is a debate about when to add doubles, but it really don't matter as long as your shorter run is at least 30 min, and you have some longer singles of about 1 hr, IMO.

Nothing wrong with your approach at all

Maybe a simple question but: is there any consensus on how many doubles a week you should do for them to really be effective?

I always remember being told when younger (before running) that if you went to the gym any less than 3x a week then it really doesn't have much effect because 2x/week was more maintenance/ too infrequent for growth etc. Remembering this just got me wondering if doubling only twice a week was too infrequent or not?

[For background I run about 120-130km every 6 days (1 day off a week) and 2 of those days I'll double for about 4-5Mi.]

Here is good explanation and perfect week planning depend on your total mileage, the best from youtube:
