I’m still waiting on my marshal route information, so I haven’t seen the route. I have ridden out from the area of Canal Park in SE to Queen Anne Farm (via New Carrolton). Here is the Strava link for that ride. Look at miles 12 to 38, ignoring the elevation spike around mile 25. Clearly there are a few climbs in the area, but I make no representation that the routing will be anything like this. 
The Honeycrisp (60 mile) route is going to be a little confusing if you haven’t ridden in the area and you better be comfortable riding on city and suburban streets. It first goes south over the 11th Street Bridge path. There no image on google maps which shows the bike route over the MLK Bridge,and I’ve never driven over the new setup and have no idea what is actually there now. There is then a good climb up Good Hope Rd SE (260 feet in 1.3 miles). After that there are lots of rollers, some worse than others. When you get back to DC after a loop around FedEx field, you have a climb up Southern Ave SE.
