Danny Mackey has athletes in the Brooks Beasts TC who race from the 800m to the 10,000m. This video covers 800 m simulations. Danny Mackey has a strong group of 800m/1,500m runners.
At 800m, he has Brandon Miller, Brandon Kidder, and Isaiah Harris. Brandon Miller ran a 1:42.19 PB in 2026. Isaiah Harris ran an indoor 800 m PB of 1:45.62 in 2026 and 1:44.23 in 2025. Brannon Kidder has 800m indoor PBs of 1:46.90 from 2025 and an outdoor 800 m PB of 1:44.99 from 2025. In August 2026, Brannon ran a huge PB of 3:33.47 in the outdoor 800 m. Josh Kerr set the WR in 2026: the mile (3:42.66), the 1,500 m (3:27.26 NR), and the 800 m (1:44:60). Waleed Suilman scored a PB at the Indoor Mile in 3:54.58 this year.
Valary Tobias (1:59.40/4:15.29 for 800m/1500m), Teagen Schein-Becker (1:59.76 outdoor, 2:01.)5 indoor for 800m and 4:04.91 for 1,500m, all in 2026) and Marta Pen Freitas (2:00.99 for 800m, 4:03:99 for 1,500m, Marta announced retirement on 10/23/26).
Here are Danny Mackey’s suggestions for success, part 2 of 3, on simulation workouts for the 800 meters.
This is a classic video from 2016 at the US Olympic Trials. We thought many coaches would like to see this one.
