tour de scottsdale - results

so i did my longest ride on sunday at the tour de scottsdale...70 for those of you who do not know how long it was. until then, my longest was 40 miles, which i only have done once a week with a riding group since mid july. since june..i do usually 60-80 miles a week. my results for the race were 3 hours, 55 minutes with only one stop at 1 of the 7 aid stations.

my results had me 40 out of 80 in AG, 454 out of 910 overall male racers. Since i don't know who was a beginner at this and who is expereinced...how is that time in general with the training ive had?
