Awesome, Chris, just what I needed (without having to do all the work!) I'll chime in over on the planning thread with my experiences from 2014 when I get a moment.
John Lee, may I suggest that you make these routes available (with appropriate provisos) for other riders (who may not be members of this group?) I assume your cue sheet is running total of miles, not broken down into days, but even still, I'd rather do a bit of math each day than try to manage the Garmin over a single 1200K file. At Gold Rush Randonnee in 2017, we were provided with just two ridewithgps routes, the outbound and inbound. I soon discovered my Garmin would load 99% and then crap out. I reached out to Garmin guru Mark Thomas who provided a hack for this: load the course, let it get to about 25% loaded or so and then.... turn off the unit. Turn it back on and, incredibly, the route was successfully loaded, ready to use. This saved us from being stuck with only cue sheets (like the "good ol' days) for the entire ride. On a related note, I've noticed quite a number of riders who won't even bother to bring the cue sheet, relying entirely on electronic navigation. I'll keep my curmudgeonly lectures to myself and simply wish those good people the best of luck...
thank you,
Jeff
