My 100th 10K run since 2018 is done today!

Come next Saturday (6/1) is the crazy “run-the-loop” full held at ’s historic : one loop is 192.37 meters, so the full course requires running 219 loops! Race starts at 5:30am 😟 and we're supposed to flip the direction every hour!

Maybe I'll question my life decisions during the run…

(still, thank you @nickwalker for organizing and inviting me)

“It was in her 50s that she set most of her lifetime PRs, too—6:01 in the mile at age 50, 19:54 in the 5K at 50, and 41:18 in the 10K at 59. She ran 1:33:48 in the half marathon at 61, set an age group world record in the mile (6:37.21) at 71, and has been hitting around 100 percent or better age-graded performances for over a decade now. “

Earned my PR today on the beautiful (SRT): time 1:48:25 pace 8'16”/mile according to . My watch again generously claims time was 1:42:49. I picked Strava to be the record.

Temp feels like 50F, dew point 47F, cloudy w/ breeze 3.2mph SW. In other words, perfect weather to get PR!

Repeating yesterday’s route aiming for making a PR on 10K, and this happened… 💩

(so my 10K PR remains to be 50:51)

9.37 miles easy run @ , also testing another pair of : ASICS Gel-Nimbus 25. Result is not good: the lateral side of my right foot hurts after the run (not during)! I blame it on the high stack of cushioning: my theory is my natural reflex to counterbalance the unevenness of the trail surface is interfered/distorted by the cushioning. Does that sound plausible?

My dear / friends: I need to ask for advise on picking for runs on paved roads and mildly unpaved trails (photo 1):

  1. ASICS Trabuco Max 2 (photo 2): the middle in weight (~290g), not waterproof. Bouncy w/ rocker design.
  2. Salomon Speedcross 5 (photo 3): the heaviest (~295g), waterproof(?). Big lugs.
  3. Nike Pegasus Trail 4 GTX (photo 4): the lightest (~270g), waterproof. Smallest lugs.

Do you have experience w/ any of these? What would you pick?

One of the stretch goals in 2024 is now accomplished! I got my latest PR in today's 5K: 21:38 at pace 6'57"/mile, thus reaching my goal of getting sub-7' pace!

Going in I was pessimistic because of the jet lag. Turns out running uphills with 1300ft elevation gains in paid off!

Next up: finish 5K in under 21 minutes!

Perhaps a bunny helped me today 🐇? After last Sunday's race PR, on my 50th 5K today I made my third PR this year: time was 22:33, pace 7’16”! This is 34 seconds faster than my last PR!

This completes my 2nd goal in 2024: earn 3 PRs in Parkrun!

My first , done! Official result was 3:51:39.8, pace 8'50"/mile. I was ranked overall 50/167, in males 40/102, or in my age group 5/9. This is slightly slower than my PR in practice (3:50:33, pace 8'48”).

But the official time didn't account for the three times I was lost (!) and had to either retract or asked people (I was not the only one). According to my watch I earned PR on marathon: 3:44:58, pace 8’35”, and : 1:45:19, pace 8’02”. (1/2)

5th time is the charm: I finally cracked my 1st sub-4h today! Moving time was 3:50:33, pace 8’48”/mile. For each half I was actually faster than my best official PR (1:55:16 < 1:56)!

Weather was typical : nagging drizzle. Temperature feels like 40F (4.4C) w/ wind 7 mph (S). Thanks to my son on the bike (he came even when losing 1 hour sleep to change), we performed no-stopping fueling twice, and I only brought two gel packs on me w/o phone.

Got my PR in my dusk run in the park: time 1:17:51 pace 8’21”/mile! Getting ready for the early March in !

Although there’s still a lot of room for improvement, I’m proud that I can actually speed up my pace now into the run! And this was done after a heavy meeting day at work started at 8am!

Bonus: I got a heart award on this special day!

Today I ran my 2nd practice run this month with my son riding his bike with me! Weather was cool with a bit of drizzle at the end, temperature was 55F (12.8C) w/ dew point at 53F.

Distance was 26.27 miles, moving time was 4:11:50, and pace was 9’35”/mile. This is 22+ minutes faster than a couple weeks ago!

“… a 2018 review noted the relationship between and energy intake being J-shaped: is dysregulated at low levels of physical activity, creating a mismatch between the energy expended and the amount of food consumed, leading to weight gain. On the other hand, as physical activity increases, so too does satiety signalling, which reduces the amount of food consumed.”

Some rough notes I can remember of:

  • Danger of using metaphors in science: neurons as toilets
  • "Deadly weapons" in the fights of seeking truths:
  • Mathematical logic: mathematical contradiction
  • Science: falsification
