Marriot Way & Waterloo Park
Warm up followed by 10 x 90 secs jogging..heart rates up to 165 max! If it goes over walk until it drops below 150. Walk for between 45 and 60 secs between However heart rate must drop to below 135.
I had planned to run this session last night but ended up going out for a meal with friends so I ran first thing today instead. First 5 reps heart rate recovered to below 135 in under 45s. Recovery down to below 135 didn’t take longer than 60s at all. Heart rate only hit 165 twice and that was at the end of a rep. I think I was surprised that the session was still about 4.5Km as I felt like I could keep going and going.
