for "converting" running speed to chess rating, I believe speed [in MPH] for 5 miles x200 works well. This gives:
14 mph [4:17 pace] -> 2800 = among the best in the world
13.5 mph [4:27 pace] -> 2700 = solid pro but not at the top of the sport
13 mph [4:37 pace] -> 2600 = might be able to eek out a living as a pro, very impressive for an amateur
12 mph [5:00 pace] -> 2400 = high-level amateur or promising junior
11 mph [5:27 pace] -> 2200
10 mph [6:00 pace] -> 2000
9 mph [6:40 pace] -> 1800
8 mph [7:30 pace] -> 1600
7 mph [8:34 pace] -> 1400
and so on. Basically, as a former hack 1850, I feel comfortable saying that once you get below 1800 in chess, you're talking about kids and adults who never quite got the hang of the game, and players between 1800 - 2200 are typically making some effort but also have big flaws in their play.

Those comparisons seem about right. However, according to Running USA, the median 5k time is 28:31 ( 9:10 pace). And the average tournament player is about 1400 (minus scholastics).
A 2200 rated chess player is above the 98th percentile among chess players and a 16:00 5k (26:40 5mile, 11.3 mph) runner is comparible to the 2200.
