I have finished my 4 week challenge. My goal was to hit a 4 W/kg FTP by the end of summer 2026. Here’s what I wrote at the start of my challenge: ‘’Hi everyone! My name is Sviatoslav and I have been cycling since August of 2025. I got into cycling because I had a shoulder injury from skiing and I need something to replace gym. I did make some quick gains but I lacked consistency in my training. The biggest disruptor was a surgery on my shoulder. I was off bike for almost 6 weeks. It was quite hard to see my friends riding and getting stronger while I was loosing fitness. But I am back:) Yesterday I did 2*8 all out FTP test and I was quite happy with my results. I thought and felt that I can hold around 230w and that what I did despite terrible sleep. I decided to take 30min nap, then I drank coffee (I almost never drink it) and put some Metallica in my head phones. Legs felt quite good. The hardest part was to pace it and hold the same power on different gradient. I don’t plan any races this year. My main goal is to increase my w/kg and reach 4w/kg by the end of summer. Maybe I am a dreamer, but I will try. With new FTP of 208w and weight of 60.5kg I sit around 3.43w/kg. I don’t plan to lose any weight, so the only way is to increase my power. I need to gain at least 34w in 14 weeks. I hope this challenge will help me do that. Good luck to everyone!’’ After sickness, I restarted my challenge and wrote the following: I am back. Unfortunately, last time my training was disrupted by sickness at the last week. I was exited when Arne offered to restart the challenge. During my first test I got 207w FTP 8 weeks ago but now I got to 227w, so I am restarting this challenge with 20w improvement (9.6%). Quite happy with the results despite sickness and travel. My main goal is to reach this arbitrary number of 4w/kg by the end of summer, currently I am at 3.78w/kg. Good luck to everyone!’’ My 4 Week Challenge Results: 95% of workouts completed as planned Result 2x8 min test 1: 252 Watts
