The Tropic of Cancer team sets off again, taking on the legendary 'Kuolai' route, a devilish hidden gem known among northern cyclists! Despite being only 80 kilometers, the total elevation gain approaches 1,700 meters. This ride also welcomes a Japanese cycling magazine editor joining from overseas. From the warm-up sprints on County Road 106, to a cultural visit to the historic Ganlin Weihui Temple, and then straight into the main climb of Kuolai with an average gradient exceeding 10%. Among the riders, there's not only hilarious bike-pushing assistance but also a luxurious buffet-level support station. However, the real final boss awaits on the return leg at Shiding's back mountain, where a relentless 17% steep ladder climb follows. How will this tearful yet laughter-filled self-torturing ride end safely?
