A PR Treadmill 5K! (Between Decent Bike Workouts)
>> Monday, January 05, 2026
New Year's day (Thursday) was spent with the boys at the ski slope. We got home that evening and I had time for a bike workout, which was about 12 hours later than my "preferred" time to workout (especially considering that I was doing this right before bed... and then planning to get up early to run hard, so that was NO recovery except for laying in bed).
I cranked out an hour and 40 minute workout with 4x10 minute efforts in the middle:
My half-mile splits were:
2:48, 2:46, 2:45, 2:44, 2:45, 2:41, 0:31 = 17:04.2
That's the fastest I've ever done that workout, and technically 1 second faster than my 5K PR! (But it's easier to do on a treadmill, I know! This is not a *real* PR!) I think my treadmill 5K PR was about 3 years ago in 17:07 where I started slower, but sped up a bit sooner.
Neither of these were reading correctly. I bet the pace at the start and finish
of the 5K effort was about right, but that's NOT right in the middle.

Then the day after that (Saturday) I hit the trainer for another decent workout. I knew I wanted to go a big longer, but I didn't know how much effort I wanted to put in (although I'm making it a point to get in more QUALITY bike workouts this year). I found myself thinking that I should do a 30 or 40 minute tempo effort, and I ended up holding on for 40 minutes. Every 10 minutes I did a different thing: 10 mins just "hard," 10 mins standing, 10 mins starting in an easier gear and shifting to a harder gear every 2 mins, and then the final 10 mins alternating standing and seated every 2 mins.
40 min effort, and then "moderate" for the next 25 mins or so.
An hour and 50 mins total.
This capped off a decent week! I might see if I can beat that treadmill 5K again in 4-6 weeks... maybe I can hit sub-17!
