His 7:43/3k pr was London last month following his 13:19/5k at Heusdon-Zolder.
In his post-Falmouth race interview yesterday CD stated he hasn't run more than 75 miles/wk since World XC back in March.
What he didn't say, is that his recent achilles flare-up occurred a week before World XC which might explain his relatively poor 24th place showing. He was in rehab for the next 6-7 weeks, didn't return to light training until about 15-20 days out from the Portland Track Festival in early June where he faded to a 13:40/5k . . . in retrospect, a pretty damn good time just racing off of past fitness.
In yesterday's interview, Chris mentions he believes he is around pr fitness now for 5k (13:08), so will train through September in hopes of getting into one of the remaining Euro 5k races (Zurich, Berlin, Brussels).
CD admitted to expecting to run more road races in the future as Falmouth was only his 3rd. However, being only 24 (birthday in October), he'll be 29 and at his peak for 2020 Tokyo Olympics & age 30 for the Eugene 2021 World Champs. By then, Rupp will have moved up to the marathon (or retired -- unlikely) so Chris should be the top US 10k guy & sub-27 by then.
Making the Eugene team in 6 years will will extend the careers of a lot of US athletes who might otherwise hang 'em up after Rio or a year or two later . . . and it will also be motivation for CD to remained focused on the track 10k until then. If he does move up to the marathon, that wouldn't happen until 2022 . . . but as someone posted above, he just might cash in his running chips at that point and start putting his Stanford econ degree to good use.
