Also interesting/sad to see that a storied 20 km race is succumbing to "(Half) Marathon Mania" and changing distance. Not surprising; the race director of the New Haven 20 km told me he thought a similar change would result in a 10-20% increase in entries. People love the word "marathon" even if it's preceded by "half."
Long ago we used to put on a One-Third Marathon. Maybe it's time to revive that event.
