Rides are getting easier and easier

Rode 103k today and found it relatively easy. Mind you the ride was relatively flat and the weather was perfect. The same ride last year was incredibly hot and I didn't think I was going to make it. I broke 1000k this year. I'm at 1089k where I was at 1061k same time last year. Considering I already had about 350k this year by the time I started riding the same time last year it's a little disappointing. 3000k might be tough considering there's only a month to train and if I do the same as I did last year I pretty much hung up my bike after the ride to Montreal.
