Hi -
Based on what turned out to be obsolete news, I was seeking the 12-seconds/10-stars reward on Repack Ridge when I discovered I was riding the very bike (Zwift Mountain) that I expected if I made it! 
Are there any current rewards associated with Repack Ridge? I’m pretty sure there isn’t a route badge. If in fact there aren’t any rewards, it seems odd that the game offers skill-determined scores - stars for nice lines - without an associated reward in drops or XP or equipment or something.
