Under your own power you and your trusty steed did 25 miles. You did it. Period. Congrats! It doesn't matter that occasionally you had to get off and help your bike up the hills. If you keep at it, soon, your bike will be strong enough to make it to the top of more of those hills. Give her time, she needs training, too!

On a related note: after a complete summer of never succumbing to walking a hill, I took a trip to Texas and discovered "Crankbender Hill". I'm never too proud to walk--better that we're out there and, sometimes walking, than sitting on the couch.

When the hills get tough, I have my granny gear; when granny isn't enough, I have my feet.
