Marriot Way from Norwich
Warm up followed by 35 mins of alternating 1 min jog with 30 secs walking. Heart rates not to go over 160 during first 25 mins and 165 up to 33 mins. Not too fussed if you want to push the last 2 reps up to 170. I will leave this one to you. See how you feel. If heart rate hasn’t dropped below 140 during 30 secs walk/recoveries, then walk until it does. If you find that initially it does, but after half way you are starting to struggle with your heart rate coming down to the desired range, then walk until it falls below 125 before continuing. Walk for 5 mins to warm down.
