15 years ago when I competed in orienteering I used to do quite serious running training. I even bought a clock with a heart rate monitor to make sure that I did workout sessions with the correct intensity.
Now when I’ve started to train for Lidingöloppet in September I bought myself a Garmin Forerunner 405cx to keep track of my running.
Today I did my first heart rate zone run in 15 years! Felt quite odd at first but in the end it was the easiest 10k run I’ve done in ages. Though it was quite hard to keep the pulse down during the longer climbs and when going down again I sometimes had to push a bit extra to avoid the too-low pulse signal. But I guess that will get easier with practice.
Hopefully I can add some kilometers per week by doing most of the running in a more “correct” lower intensity.
