Thank you all, I will definitely buy the plan. I like swimming and I am keen to put some effort into improving but living in Covid-Germany is not that easy to find open pools or lakes that allow you to swim without a total freeze. Biking would be perfect as well.
I was really searching for a plan with a strong focus on Z2 heart rate and strength after years of unfruitful training and a couple of terrible coaches. I know the start will be tough with my Z2 pace being probably around 7:30-8’/km but full trust in the process!
