McMahon’s college career got off to a bang with wins in the 500 and 1000 free against Delta State, 1000 free against Ohio State, and 1650-yard free against Texas A&M.

She struck again at midseason invites at the Georgia-Tech invite where she hit a 4:45.24 to take 8 seconds off of her lifetime best from one of the prior dual meets. Later in the same meet, she set a new school record in the 1650 free, registering the fifth fastest time in the country this year at 15:59.46.

She continued her strong month when McMahon took 2nd in 500 free in 4:39.84 behind Paige Madden at the 2020 Tennesee Invite. She followed that up with a win and NCAA leading time in the 1650 free with a 15:54.06.
