UFC bantamweight champion Ronda Rousey just kicked off her training camp for UFC 193, where she’ll look to defend her belt against fellow undefeated fighter Holly Holm.

The fight is set for Nov. 14 in Melbourne, Australia and it’s being hyped as the event that could break the UFC’s all time attendance record. Holm will look to do what no fighter has been able to even come close to doing, which is beat Rousey. If she were to pull that off it would certainly be the biggest upset in UFC history.

However, that’s a big if. The champ officially started her training camp and took to Instagram to celebrate the occasion, saying:

New fight…. New challenger… First days of training camp… Let do this #rouseyVSholm #andSTILL #UFC193 #UFCMelbourne #Nov14th
