Free RSVP Tool for London Running Clubs
Stop chasing RSVPs via WhatsApp and spreadsheets. Who's In lets you manage attendance, communicate with runners, and grow your London running community — completely free.
London's running scene thrives from parkrun hubs in Richmond and Bushy Park to street running crews across Hackney, Clapham, and King's Cross. With hundreds of independent running groups alongside established clubs, organisers need simple tools to manage everything from weekend 5Ks to weekday tempo runs. Whether you're coordinating a neighbourhood group or scaling across boroughs, Who's In helps you keep runners connected through London's changing seasons.
Challenges London running organisers face
Scattered RSVPs
Managing runner confirmations across texts, emails, and social media wastes time and creates no-shows.
Last-Minute Cancellations
No easy way to notify runners of route changes, weather delays, or meetpoint updates mid-week.
Tracking Attendance
Can't see who actually showed up or measure growth in your running community over time.
