Newbie to triathlon and Ironman, master … plausible with IM L0 plan?

Hi,

I am new to triathlon and never done one, but have set the challenge to finish the Ironman full distance in July 2022.

My background is 49 years old male, who does on average ~8hrs per week of cardio consisting of 3 bike rides (~6hrs) and 3 runs (~2 hrs). I do often long 4+ hrs rides and max run I have done was 1hr, but many 45′.

I had a few structured plans over the past few years for cycling (e.g, sweet spot, rolling road race, etc. using Trainerroad) and running ones in the past 6 months (5K and 10K from GTN).

My swimming is very weak point, technique was never addressed – but I know to swim at least 🙂

I read about 80/20 trainings and believe that I should start with Ironman Level 0 from Feb 2022 to get myself onto start line. Until then I have 2 months to improve swimming technique.

So I have two questions:

First, a hypothetical one – based upon my background above how plausible is that IM L0 plan will get me over the finish line, possibly in 15hrs – or I am too optimistic and perhaps should continue building my training and do IM in 2023, not in July 2022.

Second, given that answer to the first one is pretty realistic – what would be the best recommendation how to train for the next 2 months before starting IM L0 plan in Feb 2022 – obvious focus will be to improve swimming technique.

Thanks in advance,
Denis
