That's a scary route - lots of traffic alternating with winding roads with narrow shoulders. It's pretty direct, though - less than 9 miles. Congratulations on getting going with that so early in the season! I just took my second ride of the season, and still finding it pretty exhausting. I think I went almost 8 miles this time.
It wasn't too bad. The worst spots were where it crosses over Hwy. 100 and the part where Vernon curves and you're suddenly on Gleason. I'd biked the 50th St./Vernon Ave. section a few times before back when I worked at United Health Group so I knew what to expect there. The winding roads with narrow shoulders weren't really bad at all because the traffic was so light. I am thinking that in the future instead of taking 50th all that way that I might go on the north side of Lake Harriet and take 44th as far as I can. I suspect that will have a lot less traffic.
