One map gripe I have: They have markings for "steep hills", but don't place them in the places with steep hills. Let's get a draft from the city next time they do an update and plan a day or two to ride all the roads so we can help them properly identify the hills.
For example: Braddock Rd going west right after Russel Rd isn't marked as a steep hill--but that hill is ridiculously steep, and in the 2015 version of the map it is properly marked as such. And the part of Braddock they do mark as steep I'm not sure isn't nearly as hilly as the section they failed to mark. The small hill right outside my place on Valley Drive between Holmes and Gunston is considered steep on this year's map, while the rest of Valley Drive isn't, even though there are sections of it that are much worse than the area outside of my place (once again, it was marked correctly as all being hilly on the 2015 map...). And don't even get me started on Martha Custis, which is a giant steep hill, and isn't marked as such on this year's map.
Martha Custis isn't marked? That hill is what convinced me to trade in the 12-23 cassette on my new 1993 Bridgestone RB-1 from Spokes Etc. It's been a steep hill for decades and ain't getting flatter.Quote:

It seems crazy to me as I review old versions that, for instance, Kennedy/Landover aren't marked as steep.
In general that data just doesn't work that well for determining how steep a short segment is.Quote:

ZOMG WSGFAB and do this.Quote:

I am in for the ride.
I do not understand why hills would not be shown anyplace they exist. I have not seen the map, but I suspect it shows where there is bike infrastructure and where there is not. What would be the point of NOT showing a hill, regardless of whether the city has gotten around to making that particular street part of the bike infrastructure network?
Don’t know. I checked the Arlington map, the DC map, and the Fairfax map. Only Alexandria and Arlington flag hills on their maps and they only include hills that are on designated bike routes or that have some type of bike infrastructure. Fairfax and Washington have opted not to include hill details.Quote:

All right -- based on conversations at tonight's Fridays at the Fountain, it sounds like there's interest in doing this! Here's the plan: optional breakfast meetup at the Whole Foods on Duke Street at 8:30 a.m. on Sunday, roll out at 9:00 a.m. Bring sunscreen, a copy of the Alexandria bike map so that you can make notes about any errors on the map, and lots of patience (because I'm going to be slooooow on the hills).Quote:

Interesting, thanks. For the part of the city that we'll be riding tomorrow, I noticed that two of the places previously marked as hills are no longer marked as such on the new map:Quote:

I can't imagine that those hills suddenly got flatter in the past two years, but I guess we'll find out tomorrow. :rolleyes:
Pre-ride strategy session.

This was an absolutely terrific wonderful awesome ride. Even I (who like to ride in West Alex, and scout around for bike infra) got to ride places I have never ridden. And to ride with a group in places I have only ridden by myself. Weather was great, the company was even better. Thanks especially to Komorebi for intricate route plotting, and to Casey for added tidbits of transportation lore.
Looking forward to doing the east side.
Couple photos. LSG also scouted out some trees. Reports will be sent to the City as well as feedback about the bike infrastructure ;).
And my bike found its soul mate off Seminary Road after the pedestrian overpass to nowhere. As LSG said "It has fenders too so it's a commuter car!"
And of course lunch at Port City.
Seriously awesome ride Komo, thank you again for organizing! https://uploads.tapatalk-cdn.com/201...d24b38c401.jpghttps://uploads.tapatalk-cdn.com/201...ad6bfc2bdf.jpghttps://uploads.tapatalk-cdn.com/201...f29cfeea73.jpg

If anyone wants to ride the rest of the bike map, I'll be doing that on Sunday. Optional breakfast meetup at the Whole Foods on Duke Street at 8:00 a.m. on Sunday, roll out at 8:30 a.m. Draft route is at https://ridewithgps.com/routes/28237147. I left out Old Town, because many of us are familiar enough with that area to provide feedback without needing to ride it again.
Also, if you have feedback about the map but can't make it on Sunday, PM me. I'm collecting feedback to give to City staff. Thanks.
