its so nice to see that you are organising such an event.
the thing is me and my family[ 5 of us] went on a cycling expedition in the Kumaon region of Uttarakhand for a week covering nearly 400km. we took the less travelled roads,visiting the interiors of the state. and the journey was beyond our imagination- the best vacation we've ever had.
I would love to join you there. Uttarakhand is definitely worth visiting over and over again.
do let me know the route that you intend to take.
