Seeking advice for Desert Classic Duathlon bike setup

I’ll be riding my road bike and am trying to decide whether to use race wheels or not. I have Blackwell 100s.

Some course info:
21 miles
2-3 substantial climbs, the rest is fairly flat.

I question whether the wheels will offer more benefit then cost. I know they will help on the flats, but will I pay for it on the climbs when I am really hammering out of the saddle? Also, aero helmet???

Thanks.

I would use both, the climbs arent that steep. You will more than make the time up on the downhill and rolling parts of the course. If I was racing I would be going for the full aero setup.
