Carlos Lops (age 38 and 37 in this video). Wow!

Thanks Tom, great find!
I've always liked the stories A Cabral has posted regarding Lopes's threshold and strong distance runs, (Possibly as these continuous Tempos or LT runs are where I typically struggle), and how no one liked running these runs with him. 

Amazing to be that strong at 38!
