Serk Cycling Beijing
The fresh weather requires some ups and downs to spice it up.
For the A and B group, we'll log some serious vertical gains while still do some serious KMs. Note there is about 10km after the first two climbs that's a little bit on the rough side (nothing major), but do bring your spare tubes and a pump just in case.
The C ride is quite easy and has a designated coffee stop at the midway point.
