I'm not some super-cyclist, but a few weeks ago I did the extraordinary under my standards :) I rode for 24 miles in under 5 hours. Considering that I haven't biked in ages, this was beyond what I thought I could cover and still survive.

      Starting in Saint Paul, MN, my track took me to Minnehaha Waterfall, Lake Calhoun and Lake Harriett. Though I dressed quite comfortably, the humidity that day was intense. Every 30-45 minutes or so, I had to stop just to get a drink of water or catch my breath. The track itself was spread across roads, bike trails and some bridges. There were some uphills and down hills that definitely required my mastery of bike gears. After more than my fair share of uphills, my thighs were sore... Thereafter, I just had to get off and walk my way to the top where I wasn't going to aggravate my legs further. Hey... I'm not a pro, but I am getting there :)

      Not only was biking immensely fun, I also got the opportunity to take a few snap shots here and there of all the areas I visited. Here's a quick sample:
