basically, if you have to ask, you are doomed. \
Pretty funny, but basically correct. If you can get out and pratice at race pace conditions, then that will help. All your questions have many answers, and some will change… How many riders, distance of race, hilly or flat, how much wind, which direction, speed of riders, who is feeling good on race day, ect., ect…
In a TTT, you have to know all the answers to all these questions, and then be able to adapt to them on race day… Your strongest guy may blow up, be sick or off, you wind direction may change, then you have to peel off the other side, can you drop a rider or two for an offical time, thus sacraficing them before the finish???
Best you can do is to ask your questions, like you are now doing, go out and pratice, and go out and race. I gurantee that in every race you will learn something new you didn’t know, or even think of before hand…Good luck, they are one of the funniest races I have ever done, and the most painful…
The one thing to always remember is that, it is the fastest way to get your team to the finish that really matters, everything else is fluid and changing. It is the one truly team aspect of cycling…
