Sounds like an incre*dible fitness challenge.
Walking is indeed an excellent way to stay active and achieve your daily step goals. It's truly impre*ssive that you have not only kept up with the challenge but also surpassed your step count during a dark walk. Make sure to prior*itize listening to your body and taking rest days when necessary. Your dedic*ation is commen*dable, and I'm genuinely excited to hear more about your progress in this challenge.
