How will this shake up the US distance scene (if at all)? She will be just shy of her 32nd birthday. All of her best times were in 2019/2020:
1500m American Record 3:54.99 in 2019
3000m US #4 (combined indoor/outdoor) 8:26.66 in 2020
5000m US #2 14:23.92 in 2020
I would think she will focus on the 5000m or 10000m. Besides Monson, the closest active competitors are Schweizer (14:26.34), Andrews (14:43.36), Henes (14:47.15), Cranny (14:48.02), Frerichs (14:50.06), and Infeld (14:50.90).
Even if she lost a few steps in the 1500m, the next closest active competitors are Purrier St. Pierre (3:58.03), McLean (3:58.76), Johnson (3:58.85), Cranny (3:58.88), and Wiley (3:59.17).
