This session is great to improve speed for runners aiming for an event of any distance but it is especially beneficial for marathon runners.
Each week I will be posting the Friday Fartlek Run Sessions that you can do to enhance your running. Fartlek is a Swedish term that is often used by runners and it means speed-play. See a previous post about training intensity (levels) to know how hard to work.
I’ve written about Yasso 800’s before, back in 2015. You can read that article here. I wanted to write about that session again because I’ve now put myself through a sequence of the session over a number of weeks. I started off running four 800m reps, then a week later six of them, then eight of them in the wind and then a set of ten. A comparison of these sessions can be found after the description.
These sessions were developed and popularised by a Runner’s World editor Bart Yasso who noticed that your 800m rep times in minutes roughly corresponded to your marathon time in hours i.e. an athlete who ran 3min 800s would go on to run a 3hr marathon etc.
- 10min Warm Up Level II;
- 4-10x 800m Level V, 1:1 Work to Rest Ratio;
- 10min Cool Down Level II;
- 10min Stretching
The warm up should be done at an intensity that is steady but not over consuming at Level II for ten minutes.
The main set is made up of between four and ten reps of 800m run at Level V where you target your marathon time in hours as your 800m time in minutes i.e. if you are aiming for a 3:30hr marathon then you aim for 3:30min 800s. After you have run your 800s rest for an equal amount of time to what you just ran. I don’t get too pedantic. If I’m targetting 3:00 minutes and I run my 800m in 2:55 minutes I take the extra 5 seconds rest and have a full 3:00 minutes rest.
The Cool Down (CD) is at a low intensity, jogging (Level II) for a minimum of ten minutes.
Finish with 10 minutes stretching to assist with the recovery.
Here is a summary of my Yasso 800’s over the previous weeks.
