I was planning on making a run at Maryland or LP, but the opportunity to do it on “home roads” is too big an opportunity to pass up - even if I’ve done whatever route they’re planning a million times. Usually for these things its a struggle to shlup the kids around and find things for them to do, but if I can stay at home and stay in my own bed? Why not?
My bet is that they leverage the parkways and Mooney’s bay for the swim. There’s already a local tri that runs a few events out of there and it connects to the parkways with other minimal road closures. Two lap swim and then 3 (?) laps of the parkways. Maybe a lap of Gatineau if they’re feeling spicy -take Champlain off the parkway to get there. The run can be on one of a few of the multi-use paths (Rideau Canal - Our Unesco heritage site - anyone?) that all converge in the area, or just through the local neighbourhood as the local tri does today.
Tons of parking at Canada Post, and a reasonably close connection to the LRT Line 2 (Confederation station), if it ever gets operational again. Plus, there’s the mother of all climbing structures there for the kids, and a finish line at the Terry Fox facility.
The only question with any of the parkway routes is whether the LRT construction will interrupt.
