I will be heading out this sunday (4/20) on a 4.5-5 hr ride. Mblume has expressed interested and we are thinking of heading out from a location on the West side of the lake and head to Zug/Goldau/Einsiedeln/etc starting around 9 or 10am. avg pace around 16-17 mph.
B.Y.O food, bars, gels, drinks, spare tubes, tools to change a flat, properly working bike,etc. I prefer not to stop much save for the occasional refueling, nature calling, and photo op (sorry, I can't help myself there

)
Let me know if you're interested.
Cheers,
