During X Games in the interactive parks and around the contest of X Games, Guinness Book Of World Records Officials were roaming around in search of new records and people to break current records. They did that, quite a few times.
Abby Zsarnay decide to try her hand at a record. Most back side grinds in one minute. This all took place on the mini ramp in X Games Interactive Park. There were at least six guys and Abby. The current record was 31.
Abby matched that record. So did one of the guys. They did not get a chance to try again. So, according to Guinness World Records, Abby co holds the record and will hopefully be appearing in the next book. Congrats!
