Just in case any other TNRC-n00bz are lurking [...] here's a good idea, which surfaced [recently]:
browse the thread for links to our routes (or use the 'search this thread' tool and look for 'routes' - they're all together in a single post somewhere).
get out there during daylight hours, maybe with a few others, and familiarise yourself with the terrain/distances involved. If you can ride these routes during the day in under 3 hours (moving time), get your lumens on standby.
