Here’s a big workout during her training block:

4 x 10-minute hills

  1. 20 minutes warm up.
  2. Find a runnable hill with decent inclination (inclination depends on your own ability).
  3. Run up the hill for 10 minutes (start at a moderate pace and work your way up to about 90% effort. when you get to the top you should be huffing and puffing)
  4. Run down to where you started (use this time to recover)
  5. And do it three more times (total 4 times)
  6. 20 minutes cool down.

Tips: You don’t have to run back up to the same spot every set. Just maintain the intensity and 10 minutes for each run up is all you need.

What are the benefits?

It is essentially a longer form of hill repeats to provide a longer work out. Obviously it’s a great endurance and VO2max training. It also tests your mental resolve as it’s quite tough, and many runners often cut the work out short because they don’t want to run back up again. Tough it out, runners!

“The purpose is that it’s a long workout, working on endurance. It is getting your legs used to climbing then descending and having to get turning back over, which imitates a lot of courses, in particular TNF 50 miler, and I used this workout as preparation,” Ruth pointed out.
