I haven’t raced it by on of my athletes had a great day last year there.
Current aided “short” swim, with a rolling start. Usually WSL in October. I think you can almost float on your back and paddle lightly and make the swim time cutoff.
Hilly bike course that rewards strong cyclists that ride with discipline (ride evenly, check their ego at the door and use their gears). I’ve ridden some top AG bike splits before and nearly gotten passed going up steep hills in 70.3’s and IM’s. It’s ridiculous. Learn to be confident handling your bike on descents. It’s free speed and I think often safer than riding your brakes in fear all the way down. You bike is less stable under braking.
Run is very flat, awesome finish area, but it can be humid there even in October. Pace smart, be patient, know you abilities and trust your training.
Enjoy the journey and the training. Focus on bike fitness, and that doesn’t mean lots of long rides. It means lots of hard rides, as many recovery rides in between that you have time for and a few long rides.
I’ve done it 3x, but all my races were in the August heat. I agree with pretty much everything Motoguy says. Although I will say the current can be variable. It was definitely stronger during one of my three attempts. Also, unless they changed the swim start you swim up stream (mostly in a protected channel) before you turn and have the current at your back. That upstream part can feel long.
Ride is exactly as described. Nothing super steep but the entire course is up and down. You have to ride this course smart. Steady consistent power will win the day. The never-ending body blows of the rollers can take a toll.
Run is dead flat, not shaded, but well supported (with crowds). Not many dead spots on course
Best Finish Line of any Ironman I have done by far (compared to Placid, Chattanooga, Couer D’Alene, and Texas)
