This isn't a big deal, except for me.
I started commuting in September. It took 50 minutes to do my 8.19 miles. I've gotten faster and faster. I don't always hammer the ride, sometimes I just take it easy, so this isn't a daily test.
First ride: 50:00
Last PR: 34:50
New record: 29:35
Five minutes faster than my last PR and pushing twice as fast as my first day!
I also rode my new bike today. Usually I take my skinny tire commuter bike with light, but I'm leaving work before dark today so I took the road bike. Lack of wind helped too.
Still, it's a PR and I'm really stoked!
