<\/a><\/p>\n#29 – 50 runs in 100 days – Hardcore edition
\n#136 – 100 Days Of Miles Challenge<\/p>\n
Today it was time\u00a0 again for the running exercise that I dislike the most, intervals.<\/p>\n
I did a lactate test this Fall and my new threshold pulse is now 160.<\/p>\n
Temperature: 4oC (39F)<\/p>\n
It was going to be interesting to see what my paces would be with the new threshold pulse.<\/p>\n
I did pulse based interval training where I\u00a0will be a couple of heart beats under my threshold pulse during\u00a0the intervals.<\/p>\n
Started with 2K warmup and then it was time for my first interval where I was pendling between 155-159. It was upwind and I have a tendency to increase the pace when it is upwind.<\/p>\n
Since it was colder I decided I would jog during the 2 min rest.<\/p>\n
During the second interval I got to 161 a couple of times. Still upwind and then I have up hill at the end of the second interval where I also know that I have a tendency to increase the pace.<\/p>\n
Jogging during the 2 min rest.<\/p>\n
On the third interval I gassed to much\u00a0at the beginning and also got up to 161 but got back quickly. That is one thing that I have learned that during pulse based interval training, don’t gas to much in the beginning.<\/p>\n
Jogging during the 2 min rest<\/p>\n
Finally the fourth interval and then 1K cool down.<\/p>\n
It was obvious that it was a while since I did this last, last time was in October.<\/p>\n
The first and fourth interval were the best intervals, I survived the cold. I become troubled with a cough when it is colder but it did not bother me today<\/p>\n
