What are the most effective strategies for recruiting members for Zwift rides, and how can ride leaders balance the need to attract new participants with the need to maintain a cohesive and challenging experience for existing riders? Are there any benefits to adopting a more selective approach to ride recruitment, focusing on riders with specific skill levels or experience, or does this risk creating an exclusive and intimidating environment for newcomers? How can ride leaders use social media and other online platforms to promote their rides and attract new members, and what role do Zwifts own community features play in facilitating ride recruitment and organization? Are there any opportunities for ride leaders to collaborate and share best practices for recruitment and ride organization, and how might this help to build a more diverse and inclusive Zwift community?
