They mention CTC coming back in the news release.
For an A race, I like to have about 1-2 times the race distance. I use my race shoes for a long run and a few short runs a few weeks before the race, and then save them for race day.
If the shoe is the same version and model I’ve used before, I like to get one or two short to mid distance runs in them just to make sure there were no manufacturing variances or defects in the new pair. In a pinch, though, I’ve pulled a brand new pair off the shelf and used them in a half before.
Sounds like I am in line with most of you. I'll have about 25 miles or so on my shoes come Sunday's marathon. I've had two other pairs of this exact model and nine other pairs including previous year models. The new ones feel the same as the others did and no noticeable defects.
I agree with @camaker that the same model/size can usually just be pulled out of the box in a pinch. But usually means exceptions and I had one last week. And pun intended, the first short run of my new shoes resulted in my foot hurting from a spot in the shoe pinching during the run. The second and third runs in them were absolutely fine and I found no odd manufacturing snafus. I'm going to wear them this week for the half. Weird, but I'm glad I got in that one hurting run before the actual race.
If it is a model I had before, two or three outings totalling about 10 miles are usually enough. Maybe a bit more if it is a new model year or a variation (model+1 or light/stitch vs the normal version).
