#39 – 50 runs in 100 days summer edition
#96 – 100 Days Of Miles Challenge

Today it was again to do pulse based interval training where  am a couple of heart beats under my threshold pulse during the intervals. My threshold pulse is 163

The layup is the following:

2K warm up
4x2K intervals with 2 min rest between
1K cool down

A bit chillier today around 14oC (57F). Started with 2K warm up and then it was time for the first brutal interval. Rested (stood still) for 2 min where I drank some water and tightened my energy belt.

On the second interval I have notice that during the running on a bike path which is gradually increasing in altitude that I also increase the pace and got to 163 so then I had to run a bit ”slower” to get back to 160 where I try to be during the intervals. Rested (stood still) for 2 min, drank some water and got the pulse down.

I have been lucky so far, on the third interval I am crossing a car road and this time a car came so I had to do a short detour and the pulse went down to 156. Take some time to get back to 160, the same if I get to 163 and have to get back to 160. At the end of the interval I ran into a heavier upwind and the pace got to 156 for a short moment, felt a bit more tired here as well. Rested (stood still) for 2 min, drank some water,

Finally the last interval where I also at some point got up to 163.

I handled the increasing pace much better this time, last time I got to 165 which is above my threshold pulse, this time my highest pulse was 163. Now I feel in my breathing when I am on my way to 161-163.

Ended with 1K cool down.

Intervals is not my favorite running training, it is the most brutal thing I can do to myself but I know what it will give at the end so there is a purpose and I am improving during my other runs. Maybe this interval training has something to do with it.
