What is the fartlek method?
Fartlek is speed play (Swedish word). It's alternating hard and easy
according to feel and the objective of the workout. Note the word "play"
in there. Don't get too hung up on details and effort levels, but some
folks do tend to put some semi-structure on them. Some people will run
"hard" from power pole to power pole then recover on the next span.
Others might do a 3-6 min section hard, recover for a minute (incomplete
recovery) or 10 min or whatever (full recovery) before picking it up
again. I may run "hard" on easy sections of trail and recover on the
twistier (although my agility is improving to the point that I can make
this more tempo-ish and not have to slow down).
"Hard"/"easy" and approximate times can be whatever you want, depending
on your goal for that workout. I may use shorter timing (30-60sec, count
footfalls otherwise I go too long) if I want to focus on accelerations,
high-end aerobic (what Benson refers to as "aerobic speed" and some like
JD refer to as "no-man's land"😉 for the "hard" if I want more cardio
benefits than easy running, or medium efforts to work that zone.
Sometimes if I'm working a hill for the hard part, I may push over the
LT zone, but except for the strength issue, there's not much point for
me in running at that effort right now. For you with shorter distances,
yes, you may want to push over LT.
There's many, esp. Lydiard et al., that believe in working the full
aerobic zone. JD and others do recognize a "no-man's land" but one
runner's junk is another runner's sweet spot. But when I look in books
like Martin and Coe, they include some cardio benefits in those zones
that are more so there than at lower efforts. Granted, the "zones" are
vague and probably vary, but I do think the concept of cardio benefits
varying with different aerobic efforts is valid.
Remember true fartleks are speed play - keep 'em low key mentally.
