I need to be able to run 2.4k in about 12.5 minutes, which means I can basically do the whole run at 12kmh.

I can't do anywhere near that. I can just about run about half of that at 8kmh with a 12kmh push for the last 100/200m.

So, I'm thinking, I add an extra hundred metres to that final push every few runs til the whole thing is at that speed, then add hundred metre increments to the run until I hit the distance.

What I'm wondering though, is would I be better off walk/running the whole distance and then gradually increasing the running intervals?

Or does it not really matter?

  • What is the timeframe for this? When do you need to be able to run this distance at that speed? (Military or similar test I assume?)

    Are you ever running further than 2.4K? You'd be better off increasing the running distance and then you'll fine that the shorter distances at higher speeds become easier. Commented Mar 6 at 16:10
  • @JohnP - that's exactly it, but not in any rush, I'm taking my time with things as I've spent the last 5 years recovering from an ankle injury and many rounds of surgery Commented Mar 6 at 17:15
  • @TheFootsie - Probably at some point but it's not something I would like to do now unless it would make hitting that target in the medium term easier Commented Mar 6 at 17:16

    @ScottishTapWater - There is no substitute at all for distance. Scout7 used to say "Run. Run lots. Mostly easy, sometimes fast". That's the best generic formula to get faster at running that I know of. (As you can see, I use that a lot - fitness.stackexchange.com/questions/7309/…)
