To prepare for the Seattle Star Course, I’ve been playing with topo maps, Google Maps, and Road Warrior, feeding them different scenarios, and here’s what I’ve concluded:
1) Plan with Road Warrior, but don’t walk with it. As far as I can tell, Road Warrior is really designed for delivery drivers. It’s great for driving on errands in the most efficient order. But when you choose this path or that path to walk to your next point, you’re stretching Road Warrior outside of what it’s designed for. Despite its “walking” mode, it thinks you’re a very slow car and cares nothing about elevation. I fed it scenarios in Seattle and it always dictates the straightest possible line, even up steep slopes, and even when a flatter alternative exists. (Example: In one scenario, instead of a 2.4-mile route with only 100 ft of climb, it chose the more direct 2.3-mile path that climbs almost 400 feet!)
2) Walk with Google Maps on CYCLING mode: Cyclists terrify me on the winding rural highways near my home, where once a year I whizz around a turn at 55mph and suddenly have a near-death encounter with a slow-moving peloton. But DAMN they get things done in Silicon Valley! Because even though Google Maps shows decent awareness of elevation when you ask for directions in walking mode, it rocks at avoiding climbs in cycling mode. Here’s an example: It suggests three routes: 2.2 miles and a 285-ft climb; 2.3 miles and a 108-ft climb; or 2.7 miles and a 49-ft climb. And no traffic either.
In a side bar they provide a graph comparing the climbs:
You still need Road Warrior (or a comparable app) because Google Maps can’t handle your “hit list” of a dozen-plus waypoints. But I’d say that after you order the points in the optimal sequence, you can pretty much leave Road Warrior alone and just glance at it occasionally to reacquaint yourself with the bigger picture. But speaking of the bigger picture…
3) Paper maps. I’m going to use my paper map(s) more. When I’m tired or busy, I want to look at something bigger than my index card-sized phone screen, and whose scale doesn’t zoom in and out to the point of disorientation. And if I have time during halts, I’ll pencil in our macro-level route plan so we’ll have a tangible depiction of our progress through the course.
