I can't believe I actually did this.
I went looking to see if there was a rickshaw race in Shanghai in 2016.
Apparently not, but there was the Rickshaw Challenge Malabar Rampage 2016!
Motor rickshaws though, not the traditional variety.
FYI, @willlph , you may find a contender amongst the pool of celebrating participants. I note there are a few women amongst the beards and man boobs if you look carefully.
