So I decided I have had enough of short course duathlons and signed up for American Zofingen-Long Course next year. This will be my A race starting off the year. I have never raced this event so for those of you who have I need a little advice:

1) Should I race this course with my road or tri bike?
2) If road bike, should I predominantly train all winter on my road bike or mix it up a little using both?
3) What wheels would you use? Light weight, deep dish, disc?
4) What's the best way to pace the bike leg? % of FTP, % of perceived exertion?

Thanks in advance !!
