Derrick ran 13:40/5k at Payton Jordan a few weeks ago . . . per an email published soon after by LetsRun, CD had put in just 6 weeks of training following a winter injury.
If, say, he's in 13:30 shape right now . . . that would predict approx 28:00/10k which, presumably, he & Fernandez & Jenkins are targeting to get their Oly standard out of the way.
Surprised Jenkins is doing this.
Lagat & Rupp not running the Trials 5k . . . leaving Hill, True & Jenkins as most likely to comprise the Oly 5k team.
Seems that the Oly Trials 10k will be higher quality than the 5k with Rupp, Mead, Lagat, Chelanga, Kipchirchir, Derrick, Estrada all involved.
