Well this wasn’t specifically going to be a 10K - it was a low heartrate run for 90 minutes. But I knew (having done this quite a few times) that I probably wasn’t going to be far off 10K at the end.
A warm and humid day yesterday so I left home at about 6:15 for my warm up, which involves walking, slow jogging and faster intervals for about a kilometre. A few more stretches, couple of drills and I’m off!
I had written a simple workout in Garmin - basically one step - 90 minutes at heart rate 120 - 133. This is my Zone 1, established by a coach I had a few months ago. I still keep to it as it’s really useful. I like it as a workout because then my watch buzzes if I go above 133, and then I can slow down. Also, I can’t see my pace easily if I follow a workout - which is a Good Thing! If I notice that my pace is slow then I try and speed up, which is not the purpose of the exercise. I also have the km notifications turned off on my watch for the same reason.
I start slowly. It’s tempting just to run faster until my heart rate is near the maximum I have set, but I’ve found that it’s better over a longer run just to get there gradually as it’s easier to control later on. It was gorgeous out there, if a little warm and humid. Very few dog walkers about, but a few runners taking advantage of the early morning - all running faster than me 😬. The pond on my route was looking beautiful this morning and the resident pair of swans were lying on the grass. I didn’t take a photo as sometimes they are aggressive! I carried on, listening to all the birdsong and enjoying being outside.
Every now and then my watch buzzed to tell me I had to slow down. There are a few inclines but today I avoided the steeper ones! I could have ignored the buzzing, but I wanted to keep my heart rate in the zone today as it’s a really good exercise. I took a jelly drink at about 45 minutes as I hadn’t brought any water with me. Running slowly, I didn’t think I needed it. On longer runs than this, I would take water and Tailwind.
Getting near the end of my 90 minutes, I finally sneaked a look at how far I’d run. 9 kms. I decided that at the end of the workout I’d carry on to 10K. I pulled out a few stops for the extra .7K (which I managed at a pace of 7:07). I like to finish strong!
I was happy with the run. For the 90 minutes my HR was 132, just inside the maximum. Although I sped up at the end, it wasn’t for long. I was not tired after the run and didn’t need to snooze later on 🤣
