Winning with Altitude: Evidence from College Football

This study examines whether altitude differences between teams influence game outcomes in NCAA Division I Football Bowl Subdivision (FBS) college football. Drawing on the literature on home advantage, team performance, and environmental effects in sport, we conceptualize altitude as a geographically determined and unevenly distributed component of home-field advantage. Using data from 14,874 games played between 2001 and 2023, we analyze how the altitude difference between home and away teams affects both win probabilities and point spreads. We estimate probit models for game outcomes and ordinary least squares (OLS) models for scoring margins, controlling for team quality, stadium capacity, and year-fixed effects. We find that home teams playing at higher altitudes than their opponents’ native location have a statistically significant advantage. Specifically, teams with a positive altitude spread exhibit a 3.69% higher probability of winning, as well as an average 1.5 to 3.0 point spread advantage. This advantage is particularly pronounced when the altitude difference is extreme. These findings highlight the role of environmental conditions in shaping competitive outcomes in sport. The results have implications for scheduling, travel planning, acclimatization strategies, and competitive balance, while contributing to a growing literature examining how the natural environment influences performance in sport.
