I've been wanting to provide some type of service for a while now. Unique endurance races and endurance challenges recently caught my eye as an area that doesn't have a ton of coverage. My first idea was to jump right into building a website that made these types of races easily searchable. But I decided to slow down and just figure out the market first by creating a weekly substack newsletter. Each week I'll send out important upcoming dates for various unique endurance events and challenges. If I can grow this substack, I'll put effort into building this into a full fledged website! The newsletter is call Feat of Strength and here is the latest newsletter: https://featofstrength.substack.com/p/feat-of-strength-newsletter-8?r=g4r99 https://featofstrength.substack.com/p/feat-of-strength-newsl... I would love constructive criticism on this. What would make this newsletter more valuable to you!
