Raquel Pennington and Julianna Pena have a difference of opinions about training at elevation.
Pennington puts her women’s bantamweight title on the line against Pena in the co-main event at UFC 307 on Saturday at the Delta Center in Salt Lake City, Utah, which is more than 4,000 feet above sea level. Fighters have been known to arrive a few weeks in advance for bouts in Utah to get accustomed to the elevation, including light heavyweight champ Alex Pereira, who defends his title against Khalil Rountree in the main event at UFC 307.
