The most entertaining part of watching people speculate on athlete salaries (besides they’re usually pretty far off) is they don’t know that base salary from a sponsor is only a part of a track athletes income.
Many make quite a lot more from appearance fees, speaking engagements, bonuses in the contract and prize $. Many athletes easily make 5-15k off one race. Medals and USA top 3s are worth hundreds of thousands. Keep speculating.
