Hi Vincent, welcome to Forumosa and an early welcome to Taiwan! Let me answer your questions one by one…
It is normally Saturdays, however, if weather doesn’t look good, I move it to Sundays. For the upcoming weekend, I can’t promise anything, but I will keep your rental situation in mind and have the ride posted as soon as I can!
I will post the ride info as soon as I can. Sometimes work and discussion on the route takes a few days.
Meet up times are early, so there’s very minimal traffic on the roads. You should be ok. We normally meet near the National Palace Museum. However, don’t worry about that for now, meet up locations will change.
We all can’t ride at the same pace going up since everyone’s fitness level is not the same, but we always wait for people at the top and won’t leave anyone behind. No worries!
