I found a local cycling club – The Puyallup Cyclopaths
They put out a schedule of weekend rides, though this starts in May and is mostly for routes in the currently snowy passes around Mt. Rainier that will be open later in the season. I caught news of the club on Strava, commented on a ride, and pretty quickly had multiple emails welcoming me to the area!
The route up Mowich Lake Road proved to be a great ride with a good view, and Leon led the way and was good company.
My second ride with someone from the club was with Mike to his infamous “Climb” route which is a 5-mile climb. Apparently they often meet there to do hill repeats, going up and down the same path a few times to get some extra climbing in. I’ve never done hill repeats, nor would I normally seek them out, but to have company on a ride and enjoy the views made it worthwhile.
