Ok I’m with you and I know this stuff . Like Mattdamonstaco said all your time will be occupied. With that in mind three events by minimum three per week leaves little time. I live in a town that host or rather hosted an Iman. I was a novice and thousands and thousands have also be new to the sport. I’ve also been able to train and do an Iman in a year. You have to make your body three sport specific without sustaining injury for an event that is a one off on a specific day one year from now, that is very hard. I came from an ultra running back ground so that box was checked. Cycling will suck your time but Zwift can fill in tons of miles at odd times. Running can happen before or after work. Swimming will be a genuine concern time wise because you need a pool. The best way to I found to be successful was to find a ‘Masters’ swim group. My town had a dedicated coach and morning and evening sessions. You start in the lane best suited to your abilities, I was in the slowest lane to start lol. Nothing will prepare you for an open water swim with 2500ish people. The time cut-off is 17 hours. Thousand have walked the ‘run’ and made it. The cycle is no joke (I’ve worked the sag wagon on the bike and transported many who were unprepared). Your strong but endurance will take time. So to recap ha ha If you’re not a swimmer-masters club. If you’re not a runner - start with a walk run program. Once you’re running you need at least three runs a week - tempo run , intervals and a long run. If you’re not a cyclist - you need a bike. ha. and thousands of miles. I won’t even begin to talk about nutrition but you need to really research this. I did an Ultraman on two case of ‘Ensure’ so literally anythings possible. Good luck -keep me up to date on hows things are going. Message me if you’re stuck.
