The all important pre-ride briefing innThe Swan’s courtyard. You can see why we need to get the ride out before we open Bike Kitchen just after 11am.
Negotiating an A frame barrier. It’s easy if you’re able bodied & ride a bike with narrow handlebars. Imagine trying it if you had mobility needs & had no one to help you.

All 3 groups assemble in Hershel Park, Slough, for fun facts on astronomy, famous park residents & the impact of Michael Fish’s hurricane.
Another massive Level 1 easy guided ride from @theswanclewer.bsky.social today. We negotiated the barriers to get onto, & along, the Jubilee River path. We rendezvoused in Herschel Park, Slough, for our last impromptu talk about the Herschels ☄️ 🔭. Back next week for a longer Level 2 ride.
