Wesfly - did a 100Mile run just to see if he could, then did an Ironman on not much training and qualified for World Champs (currently training for that but isn't until Oct '23). Has made some loose IG posts about not being done with his track career but who knows really. Has more recently been trying to promote his coaching services on IG.
Zach Levet - got a shoe sponsorship(not an actual athlete contract obv) with Hoka and then didn't maintain his running, left California to go to Texas to be with an old buddy, and yes got called out on stitching over and reselling Nike products. His IG aludes to him having worked on/with Ryan Trahan on hi '30 videos in 30 days taking a penny across the country'-series. Probably currently now just dealing with the fact he dropped out of college and needs a job.
TAS - seems to have given up on his Dad's training, says in a few YT videos that he's being trained by Ari and now keeps going on about Jakob-style LT workouts. Ran his hometown Turkey Trot today in 24:32(5M) but hasn't been very forthcoming about what his plans/intentions are now. Probably doesn't help that his partner has also called it a day on her Pro Career (although obv for different reasons)
