They all ran a half in Costa Rica. Ryan won last year in 65:xx. Site in Spanish and I am unable and unwilling to dig further. NAZ Elite Twitter posted results.
Sara Hall also won the womens race.
Not the deepest race in the world, or the fastest. Apparently it is at some altitude. Glorified training days for most.
Llano just ran his debut 2:17.xx. Ryan Hall, due to LetsRun logic and transitive property, is in worse shape than his Boston race. maybe sub 2:20? He said after his ten miler he was not in the best shape. Abdi is in even worse shape. Could he even beat Shalane heads up?
