Nike Zoomfly Flyknit

Training choice for the VaporFly.

Sizing: True to size (stretch to fit)
Insole: Removable
Arch: Don't need to use currex insole
Weight: 8.4 oz
Recommended use: Tempo, interval, faster paces

Pros:
  • Noticeable bounce from carbon plate
  • Snug fitting upper that takes time to stretch
  • Don't notice the weight (though some reviewers believe it is bottom heavy)
  • Use primary for less than 13.1 miles, but have used for over 17 miles
Cons:
  • Shoe lace doesn't stayed tied, need double knot
  • There isn't much heel outsole, so I am constantly applying shoo goo 
  • Heel can feel unstable

The fit on this shoe required break-in.  Likely 1 run should dial it in.  I go for this shoe whenever I am trying to run faster paces (i.e., < 8:30 min/mile for me).  I like the cushion and the pop from the react/carbon plate.  I have used this shoe in this size with the OEM and the currex insole. 

The carbon plate gives this shoe more pop than the Epic React and more protection in the forefoot than the Pegasus Turbo.  I am not clear this is the best shoe for hills, but I have used them on hill training.

I highly recommend this shoe for tempo/interval training.  Especially since it is on sale right now for under $100 (I got my 2nd pair for $65).

Comparisons:

Adidas Glide 8 - Zoomfly FK for the win on faster runs.  It is a lighter shoe with more bounce.  For easy, more relaxed or hill runs, the Glide 8.  

New Balance Beacon - Toss-up except for hills.  I prefer the Beacon for hill runs.  

Nike Pegasus Turbo - Beacon is the winner.  The Turbo's forefoot degraded after 150 miles and the shoe became unusable for running.  It is also a very soft, bouncy shoe as compared to the Beacon.  Outsole is also not as robust.  Additionally, it is significantly more expensive.

Nike Vaporfly FK -  VF FK for the win.  Under all usecases, the VF is the better shoe, except for price.Train in the Zoomfly, race in the VF.

Reebok Forever Floatride Energy - TBD.  Much potential as it feels like boost, is almost 2 oz lighter, and the upper is much simpler. 

Skechers Razor 3 - TBD.  I haven't run the Razor 3 past 10K yet.  Normally, I go for the Zoomfly due to the fit, drop and consistent energy return.

Skechers Ride 7 - Zoomfly is the winner except for easy, hill and long runs.

20220206 Stryd Pod Calibration Change

 So, it seemed obvious today that the pod was still off.  It seems to be reading short of the intended distance based on 7 mile circuit and initial readings on my 11 mile run today.  I feel like .20 miles short on 7 miles.  So .0286 miles off per mile.  Current calibration is 99.3.  Reset to 100.  Current calculations indicate 102.25

Finding a Running Coach

So, I decided that I wanted to try to find a running coach this summer to help with my marathon PR.  I started by reaching out to a coach that reviews shoes on 2 websites that I go to.  After a 30 minute discussion, I wasn't totally sold.  He was nice enough, but he lives in CA (so no one-on-ones), and wanted some level of commitment to his plan/schedule (i.e., his workouts would trump other training, like my Striders' marathon training).  His costs were $325 per 3 months. I then reached out to a coach on another website.  Most of the coaches had significant running experience.  I had a free consultation with the recommended one for me.  It was a nice conversation and he was more flexible than the 1st individual.  Cost was $60 for a plan, $39 for a consultation or $189 per month for more one-on-one work.  He lived in OR, so it was video conferencing one a week.  I was ready to try him out for a month, but I sent some final questions to...
