"Lynn Valley Loop" trail online (very useful website, btw) as an easy going trail that could be completed less than a couple of hours, and was fine to hike year round.
There is much evidence of the the logging that was done in this area. There are many large stumps with the platform notches in the side of them where loggers placed 2x4s to stand on while they worked each side of the saw to cut the tree. It's a common site along trails all over the lower mainland. I would love to hike in an old growth forest that had never been logged.
I just recently signed up for my first trail run. It's only 5 k, but I thought I should start small since I don't have much time to train on trail and can't do long distances on trail without a partner (gotta find a trail running partner!). The 5 k is actually called My First Trail Race and is in this same area where we hiked, so I'm going for it. I hope my trail shoes arrive soon!
