Tip: go early to beat the tourists.
Tourists swarm the beaches of Lake Okanagan from the late morning into the evening. So to get the best running experience, go early, or pick a cold day.
I was running along the beach by 9:00 on a weekday and it was very quiet. I started at one end of the beach, running along the beach side pathway, along the pier, past the out door patios of the hotels, along the marina, and past the tennis courts to the natural treed area along the waterfront behind. On the way back I ran through some of the residential area and then along the beach again to get back to the start.
The city has done a great job with the waterfront, keeping it accessible and clean, and open to all types of users.
I turned around at the 5 k mark making this a 10k run with absolutely no vertical and absolutely no wind.
