Today I have finished my 4 week challenge. My goal was to improve my 15min power. I did the same 2x8min test as a month ago. Here’s what I wrote 4 weeks ago: "Hello, my name is Justas, I am from Lithuania 🇱🇹. I get dropped on group intervals sessions so my goal for upcoming 4 weeks is to improve 15min power. I did the 2x8min test and the average power is 323w. I will do the same test after 4 weeks to see if there is a change. Wish me luck :D" My 4 Week Challenge Results: • 93% of workouts completed as planned • Result 2x8 min test 1: 323 Watts • Result 2x8 min test 2: 353 Watts • 9.3% Improvement • FTP from 291 -> 318 Watts **How do you feel about your challenge?** I am very happy with the result, did not expect such improvement. **What did you learn?** Training becomes easy if you have a plan. **Did this challenge help you move closer to your goal? Please explain how it did or didn’t.** I improved my FTP, I got stronger so hopefully I wont get dropped that easily :) **What about this challenge did you dislike and/or like? Please get specific.** I did not like the upper 120% time limit, however it makes sense **To whom would you recommend this challenge?** To anyone who want to improve.
