what's the longest race that has exactly the same route ..

Or is that not exact enough?

RAAM?

Paris Brest Paris has had the same start/turn/finish since 1891. However the route has changed considerably over the years. (Technically not a race, except that the 'winners' always get their photos in equipe etc. and the pros stopped racing it in 1951)

Well if we're going down that route (but really getting away from Pro Racing), then http://transambikerace.com/ is longer again. Though the route has only been around since 1976 (and the race only since 2014).

My intended goal for 17/18 if things go well in 16.
