They say they're leaving at 9am and returning via GO train by 7:20, so I say they're averaging about 20km/h or so (rough estimation). Here's exactly what they wrote:
'Third annual one-way ride to Niagara Falls with return by GO Train. Optional escarpment climb and descent. Return via GO Train at 7:20 pm (check schedule online before leaving Toronto.) This ride is most suitable for Tourists and Sportif, but is open to anyone who wishes to join. Check TBN website August 5 in case of cancellation due to rain. Meet for a 9:00 am departure on the NW corner of Queen's Quay and York Street.'
According to this:

They're eating at the 80km mark, and if going at 20km/h, they'll be eating within 4 hours. I usually eat by the 3rd hour, so this might be a problem. And they're having water at the 38km, 55km, 110km, and the 130km mark.
Go train seems to be a $18ish fee going back. I wonder if a round trip is possible (probably not, almost died on a 80km round trip -160km total- to Hamilton last time)
Seems like you're the coordinated, so any extra words on the past experience, age group (yes it matters), people being dropped, etc, would be greatly appreciated.

But wow, there's a lot of organized groups, I should start showing up to some.
