We are a family of four who did the PEI trip last summer. Our kids were 9 and 11 when we took the trip. We had taken two two-day trips to prepare for the trip, as well as some training runs at home. The kids enjoyed themselves, especially since all the adults seemed to take them under their respective wings. We took our time along the trail, and took many breaks. We were usually the last ones to arrive at the campsite, but somebody has to be last!!
What you are doing is priceless and I’d do it again.
Make sure you bring plenty of film -- as well as plenty of warm clothes. You may not need the warm riding stuff at all, of course, but just on the chance that you encounter the weather we did --
The scenery is out of this world, really.
Your chosen routes clearly had scenic and low-traffic advantages.
Congratulations on another fine trip. The tour allowed sufficient opportunities for additional mileage. The tour gives back more than what is paid for. Looking forward to next year if I can make it.
