Dear LRC,
I’m a 15 year old middle distance runner and I am really interested on improving my top end speed , ideally I can incorporate this into my base phase , on an easy day. This will be in addition to a CV session, a tempo run, and a long run each week.
What should a speed development session look like?
What should the warm up look like?
Does running a long cold down afterwards take away the benefit of the short speed?
How should this progress throughout the season and annually?
I it necessary to do this type of work every week?
How should it fit in to a training week?
Can it be done year round?
Thanks
Sam
Those are really good questions and approach that will help you maximise your potential over middle and/or long distances as well.
The warm up should consist of warm up run, drills, several accelerations/strides. Warm down length depends on what your body is accustomed to. It might be 2k for wu and wd, might be 6k for each, probably something in between depending on your milleage. Generally, I would suggest adding speed development session on the day before your endurance session (threshold, tempo, CV that kind of work) and when you are pretty fresh. That might be start of the week, that might be middle of the week, depends on your schedule.
Early in the season, especially if you are only introducing this kind of work, do hills instead of flat sprints to minimize injury risk. Once you get accustomed, gradually transfer into flat work. Progression could be something like starting with 4x6-10sec hills with full recovery (at least 2 minutes). Then you can do some flat, some hill sprints, say 3x60m flat + 3x6-10sec hills,then transfer fully to flats with sessions like 30m flys (where you accelerate 30m, sprint relaxed at max speed for 30m and then deccelarate, 60 meter sprints (someone linked to really solid thread above), 80m, 70m, 60m, 50m, 40m cuttdowns. Coming from general preparation period, I would suggest adding 1-2 longer sprints in addition to short ones, to get some feeling on what it feels like to hold close to your max speed. These should be not all out, but really fast, again full 3-5+ min recovery. So session would look like 4x30m flys + 2x150m. Those longer sprints could be anywhere from 100m to 200.
Few notes, hills are more if introduction as you improve your body’s ability to recruit muscle fibers, but it does not work on specific speed mechanics and recruitment patterns as you are doing it at slope. Again, principle of specificity. Secondly, running start is better than standing start, it will decrease chances of any achiles or other injuries and again as middle distance runner, the acceleration phase is of less importance to you then sprinter.
This should be done year round, every week or every two weeks or whatever your microcycle is. I personally prefer every week. From my experience keeping in touch with your max speed also decreases injury risk as well.
To comment on some of the comments that it is not beneficial. From theoretical numbers standpoint using the ones provided by LateRunnerPhil who is a 30 something person and started running few years ago, so credibility is in question there. If you improve 100m by 0.5s say from 12.5 to 12, then your 200 will go from something like 24.5 to 23.75 and your potential for 400 will improve from 52-53 to 50-51. Those are approximations for middle/long distance type runner but one can see the trend.
For inspiration, suggest checking Justin Rinaldi (fast8tc) on instagram or his posts on letsrun. His group is specializing on 800 with less emphasis on milleage, but the sprint work/sessions should be similar regardless of focus.
