I Trained Twice a Day To Prepare for a Marathon. How Did It Go?

And should I continue this madness?

Late last year, I decided to join the Holmenstrand Marathon in April 2024. Since I had more than three months to prepare, I started an 18-week program from the Nike Run Club feeling good. However, I also wanted to retain all the muscles I’ve worked hard to build. I still remember how hard it was to regain the strength I lost when I stopped doing resistance training for ten weeks.
