if you have a Half marathon on this spring’s calendar, you should include a “fitness elevator” workout in your training schedule. A fun twist on a fartlek session, this workout allows you to get faster and faster to practice running on tired legs, a must if you want to finish strong after running 13 miles.
The fitness lift
The purpose of this seven-to-one workout is to progressively increase speed as the intervals get shorter. So you should start the first seven-minute section at about your ideal half-marathon pace, or a little slower. Increase the pace with each subsequent interval so that by the time you get to the two-minute and one-minute sections, you’re moving at about a 5K pace.
The recovery period between each interval should be half the interval that preceded it, so after the seven-minute section you rest 3:30, after the six-minute section you rest 3:00, and so on. Should try to do a very slow jog during your recovery periodsbut as the pace gets faster, you may need to slow down even more to walk.
This is a fairly large workout (the actual part of the workout without warm-up and cool-down should take more than 40 minutes), so it’s more suitable for a more experienced runner. If you are a relative beginner and this is your first halfyou can shorten the workout by starting from the five-minute mark, but make your warm-up and cool-down slightly longer.
