how far will they climb, and what route do you take?
my son will happily jam up to the dead moped trailhead, but getting him beyond that can be tricky
one day soon i will leave the dog behind and introduce him to the wonders of bus shuttling
They are now running 30t N/W rings on front with 11-36 9spd on the back, so they have a pretty good gear for Burnaby, especially with 24" wheels.
So we typically ride up the North Road Trails or PowerLines up to Joe's/Trans Canada. They can then ride that without support to the last switchback prior the junction with Cardiac. We take a couple breathers along the way. Then we just hike up cardiac and they ride the final switchback to the ringroad, or we carry along Joe's to campus, which they can ride most of with a couple more breaks.
We hope they self-realise the positive benefits of the ride up may actually be more important than the ride down. The fun quota flips the other way for the DH segement obviously! somewhere in there, there must be some kind of life lesson as well. Or they'll just consider us mean SOB's…
Either way, we'll toss the coin.
Edit to add: I think they see me do it as a daily commute, and have seen this since they were babies, so their frame of reference may be skewed??? And we are not anti-shuttle zealots either. If it's late and we want to bang a quick lap or we can get an extra lap, we'll shuttle one with either me or the Mrs going back up to fetch the car.
