Over the years of racing and doing long course triathlon I have learned that dialing in your bike for these distances require some thought because out on the course triathletes need to be self-sufficient when it comes to nutrition and having a plan for a mechanical error. A slight mishap in nutrition or a mechanical failure will certainly end your race quickly.
I use two salt stick pill dispensers that I zip tie between my aero bars. I take one capsule per hour. I really like having this available. The salt stick dispensers are easy to twist and pop out a pill rather than trying to dig in my top tube bag or back pocket when I need my salts.
I use the Garmin 500 cycle computer that I mount to my bars as well. Although the front end looks cluttered its aerodynamic and fits between my arms really well.
I only use GU because it’s the only nutritional product on the market that works for me and my stomach. The subtle taste makes drinking much easier on a hot day when my stomach will not take in much. I keep one dense bottle of Roctane on my down tube and keep several gels taped to my stem between my aero bars. Again, I like to have everything right in front of my face as reminder to fuel often.
I really hate flat kits. I don’t like trying to figure the best way to carry them aerodynamically and after months of trying to figure this out I gave up and simply strap two tubes with valve extenders already installed along with to C02 bombs ready to go. I use black tape to attach the tubes to my seat post and secure them down with a Velcro strap. So far so good, the flat kit sits nicely behind my thighs and away from the wind and it’s easy to access and put back together.
I have two sets of wheels, ZIPP Sub 9 disc and 808 front. I also use HED Jet 9 FR's as well. For Wildflower I will use my HED Jet 9 FR’s. These are very fast wheels. However, the front is pretty deep and I am hoping that the cross winds will not be that bad, I can handle front end nicely but hope Mother Nature is nice. I am not oblivious that deep dish wheels dont like cross winds but these wheels have worked for me on similar terrain. These wheels are better suited for fast short courses over a mild less hilly terrain but also serve well as an all-around wheel set.
I will be using my Dura Ace 11 speed Mid Compact crank Wildflower is notoriously hilly and a mid-compact crankset should work just fine.
