Today is a rest day on my half marathon fitness blueprint.

Yesterday I completed the 6o minute extensive interval programme and used RPE (rate of perceived exertion), but I also used a heart rate monitor and kept an eye on what my heart rate was doing when I was self regulating in the RPE zones of 7, 8 & 6.

In my first 20 minutes it fluctuated between 145 and 156 beats per minute.

The next 20 (RPE-8) was between 155 and 165 and the last 20 minutes (RPE 6) was 125 to 140 (apart from the last 2 minutes when I was accidentally sprinting and working far to hard to even look at what my heart rate was doing!)

Tomorrow is the first of the long runs – 6 miles – so I’ll let you know how it goes.

Monday is another rest day, but I’ll be discussing some more issues around heart rate training.
