Best way to fix tubular during a race?

What he said ^^^ is what I do as well.

I sometimes forget to take pit stop out of my pocket after bike..need to get better with that...doesn't fit in my saddle bag with the spare tubular.

I bought an inexpensive tubular at Performance tire now I just use an old one that I no longer use. Be sure to prestretch the spare by putting it on a rim of any type.  Also if you need a valve extension get one and have it attached to spare so less fussing with stuff if you get a flat.

My preference would be to ride clinchers but I have Zipp 404s with power tap hub so I'm not changing any time soon.

Good advice above and exactly what I do. I always have a tiny razor blade electrical taped to the back of my seat post. If I need to change the tire, I'll just cut it in half, stick my finger inside the tube, and rip it off. Then just put a pre-stretched spare on without glue/tape and CO2 it. It should stick well enough to finish a tri at a good pace but I'd only take curves as fast as I'm willing to crash because there's no guarantee that the spare won't roll off the rim during a curve.

Do either of you pre-glue your spare tires?

My spare is an old tire that I used for a season (or two - don't remember) so it was pre-stretched and pre-glued.  I would definitely put a coat or two of glue on a spare after stretching it if you have never riden that tire before.

However, rather than purchasing a spare, check around with other athletes, bike shop, etc; you may be able to find one for free/cheap that someone had changed out and is willing to part with.

I don't. I've flatted a tubular before and the spare seemed attached well enough IMO to finish a tri as long as I'm careful on the curves.

I put one layer of glue on once a season.
