Is there a reliable/dedicated path on the east side of Lake was that I can take all the way back to Seward/Genesee? I've never run the east side before.
Basically... run!
There's a decent route on the east side along Lake Washington Blvd (streets and paths). I've been as far south as The Landing and north almost to I-90. I assume it's easy enough to get onto the I-90 path, but I don't know about going around the south side of the lake.
