As fate would have it I have two tests that obviously are hard to draw conclusions from.
10 minute warm up 3x4min @5k feel race pace.
I’m my Cielos I had just done a 60 minute very easy pace on the bike trainer 40 minutes earlier. I felt very warmed up in a good way and the first interval came pretty easy on the Cielos
3:55/km
3:50/km
3:52/km
3:49/km
It was 90F degrees outside and in the morning.
Then today, it was 108F degrees, and I prefaced my workout with a hamburger, broccoli and watermelon 40 minutes earlier. Heh. Not exactly scientific comparison.
Same workout only I was wearing the Alpha fly 3 for the first time.
Wow, I really like these. My first interval I looked at my watch and felt I might be working harder here from the recent food and the heat… But then suddenly it was smooth sailing and here were my splits on the Alpha fly 3.
3:52/km
3:44/km
3:46/km
3:39/km
Each interval in both shoes I did two 180 degree turns U turns.
The conditions outside and in my body felt worse, but not miserable. In between intervals in the Cielos I happened to have my wife and the jogging stroller next to me with a ice cold water bottle and with the Nikes I didn’t have any water.
Definitely not scientific enough to be a real comparison but it was interesting nonetheless as I just happened to do these same workouts on back to back days in different shoes.
I would say the Alpha fly 3 handles really well. Felt grippy, comfy, fast. I’m not really sure where I can fault it*. Much more stable (to me at least) than the vaporflys or previous alphaflys.
*Other than Nike’s ridiculous production and sales strategy…
