The Atlanta Trials showed that there is tremendous pent up energy in the running community for a big shiny goal, a BQ for the people whom the BQ is not a challenge.
The Trials needed some tweaks, but not a makeover. 2:20 and 2:40 would have gotten you aprox. 300 runners per gender, a marginally smaller field size to 2020 but but not the mismatch of 200 men and 500 women in 2020. The Atlanta Track Club lost a ton of money in 2020, but you don't need to cover airfare and lodging for every runner, just do it for the A qualifiers. The water-bottle situation was a mess in 2020, but again just give custom bottles to the A qualifiers, the B qualifiers can do a normal cups of gatorade, water, and gel packets
A 300 person race also is not going to cause crowding issues for the top runners either.
Finally with the faster standards the final qualifiers are going the be the amateur professionals. The people putting off real life to dedicate themselves to running for a couple more years... kinda depressing. In 2020 the final qualifiers were the professional amateurs, those who are not putting off the rest of their lives but continuing to run at a high level... totally inspiring!
