Distance 35km [total: minimalist 285.6km: Barefoot 4067.9km] Week49
Wednesday, 12-Dec. 7kmWith a hot Adelaide day ahead the only option for running is in the early morning. I set my alarm for 5.25am. I had hoped to get to bed early but as it was our cinema night last night I didn't get back until around 10.30pm. When the alarm went off I still felt in a daze, I got myself up and had a glass of carbo fuel. I got to the beach at 5.40am.
It was calm at the beach, no breeze and definitely no strong sea breezes that normally pick up in the afternoon. It was around 28C as I set off for my run along the small strip of wet sand left by the receding tide. The sand alternated between firm and quicksand like. I ran on the sand to spare the blisters on my foot. The sun had just popped over the horizon at after 6.05am, the hills keeping me in shadow for 10 minutes after sunrise. A good run but hot work.
Thursday, 13-Dec. 10kmEven hotter night with the temperature still around 30C outside at 12.00am. I kept my windows shut as the inside temperature was almost the same as outside. I got my fan up and running for the first time this summer. I got to bed at around 9.30pm but it was a restless night. I did feel better this morning when I had to get up. It was around 25C before dawn, slightly better than yesterday. I ran along the footpath this time as there was very little sand to run on. I was careful to make sure I placed my feet correctly at each step so I didn't take the skin of the blisters. There were quite a few runners out this morning and I used a few as targets to catch. My heart rate was higher than normal at around 145bpm, probably due to the warm still weather.
At around 1pm, during my lunch break, I took the opportunity to do some surface temperature measurements using a digital IR probe with laser targeting. The ambient temperature was 35.7C.
So the results, which I averaged over around 8 measurements were as follows:
- Brick Pavement = 54.8C
- Bitumen = 59.1C
- Concrete = 54.0C
- Grass = 32.0C
The values I recorded 3 years ago with a hotter ambient temp of 37C were as follows:
- Brick Pavement = 48.6C
- Bitumen = 41.9C
- Concrete = 44.0C
- Black path = 49.3C
