Pulse based interval training

#14 – 50 runs in 100 days – Hardcore edition
#121 – 100 Days Of Miles Challenge

This afternoon it was time to do pulse based interval training where I am a couple of heart beats under my threshold pulse during the intervals. My threshold pulse is 163, I hoped that the sun would come out but it looked like that wouldn’t happen.

So it was just to head out and get those intervals done. When I started with warm up part of me wanted to quit and head back home but that wouldn’t happen. The weather was grey, upwind, rain from time to time. I am not very found of rain and upwind but it strengthens you as well.

The layup is the following:

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

Temperature: 15oC (59F). Started with 2K warm up and then it was time for the first interval which was the best interval. Rested (walked) for 2 min where I drank some water

The second interval I landed at 156 and lay there for a while, eventually I got up to 160, during this interval I am running on a bike path which is gradually increasing in altitude where I also increase the pace and got to 162 so then I had to run a bit “slower” to get back to 160 where I try to be during the intervals. Rested (walked) for 2 min, drank some water. This was one of the toughest intervals. Here I started to feel a relief because I had done half the intervals

During the third interval I got up to 160 pretty quickly but was after that pendling between 156-159 but got back to 160. Rested (stood still) for 2 min, drank some water,

Finally the last interval where I also had a hard time getting up to 160. Also one of the toughest intervals and I just wanted it to be over soon.

The interval training today was tougher. The reason could have been that I still was tired after the fore foot running this weekend where I get very tired calves after 20 min fore foot running.

Ended with 1K cool down.

I hope that I can do one more pulse based interval training before the resting weeks before my last race this year
