I was able to catch a few things today in between studying for exams. It's not super extensive, as it's just bits and pieces of information and evidence, but hopefully this will help:
At Harbour Green Park, I noticed several two-person kayaks (it was difficult to tell how many there were but it looked like 5), which would fit in with the tweet regarding teams "running down Denman with paddles and life jackets." I was only able to catch one team (male/female) there, who were possibly the last team. There were people packing up after they left, including one camera man (I'm not sure if they were production or some news channel) who was getting shots of the boat flags. They left the area around 11:30am and went up to Hastings St. I'm assuming they hopped into a taxi as I had lost them after walking up Bute St. I did manage to see something blue in their hands (Route Info?).
I then headed up to Grouse Mountain, where I found some teams heading up/down the tram. At about 1:20, a male/female team came out of a tram. I overheard the female yell to their taxi driver something like "this is the finish line," which I'm assuming was the Pit Stop for this leg of the race. I overheard a woman and her kids saying something about Crab Park, which may have been the Pit Stop location. This team had some problems with money (they didn't have enough) but left Grouse within 10 minutes. I'm not sure if they begged for money when they entered the Starbucks or not.
During this time, a male/female team had just arrived at Grouse Mountain. (They may have been the team I saw leaving Harbour Green Park earlier)
The other team I saw was a female/female and they had just got off the tram at about 1:30-1:35. As they were running to the taxi, I spotted one of the teammates holding a red Roadblock clue (Grouse Mountain=Roadblock).
After the female/female team left, I stayed for ~20minutes but nobody else came down during that time. Unfortunately, I wasn't able to stay any longer to get a glimpse of the other teams or head out to Crab Park. I was able to get some pictures but some aren't that great due to the distance and angle.Pictures:
