This Saturday's (4/28/12) Tour of the Tucson Mountains was the 26th consecutive year of the popular event.
Unfortunately, due to low attendance (+/- 800 riders) and $$, this tour is being discontinued.
Rode it about 24 times, both on our tandem and on my single bike.
Always a great event; sad to see it go!
Tour of the Tucson Mountains never had that many entries; largest we recall is about 1,200.
Perhaps you are confusing it with the El Tour de Tucson that usually has 8/9 thousand entries?
