Learn how to embrace the pain to get stronger (good pain, not injury pain).
Just ride your bike for fun—get more comfortable on your bike in all types of conditions (be smart).
Practice scenarios similar to race day. Set up your bike, wear clothing, wear HR monitor, stuff jersey pockets, etc., similar to race day to get use to what "it" feels like.
Be sure to have a bike that fits you—don't buy a bike and then try to fit it.
Trust your mechanic. Be sure your mechanic understands your individual needs and goals.
For most triathletes, there is no reason to be "aero" on the bike with a flat back. Avoid an aggressive aero position on the bike and get a Retul fit by a fitter who is qualified to fit you with the Retul system.
Know how to dress appropriately on the bike and invest in comfortable shoes and helmet.
Use your gadgets appropriately. Use a bike computer, separate from a running Garmin so you can fix it to your bike and not on your wrist. Rather than being stuck on speed, consider lap times every 10 to 30 minutes so you can better pace yourself.
Create sets that will allow you to progress with fitness and remember that athletes will peak at different times.
Do not get frustrated on the bike as cycling is one of the best activities that you can do for a lifetime (like swimming) that is easy on the body.
Ride safe, wear a Road ID and have fun!
