Yesterday started out as an overcast and slightly cooler day. I decided it was a good day to see if I could make it to my self-defense class on my bike. By car, the distance is 10.5 miles but I knew it would be slightly longer taking the winding curvy bike path - well worth it to avoid traffic and traffic lights.
I hadn't planned to do this ride yet so I had not charged my electric battery to full capacity. I'd already used almost 3 amp hours out of an available 10. This made me a little nervous as I originally intended to have the option of using the electric assist to get me there faster and to get me home after a tiring class, speed being important in the hot part of the day.
As the weather was a little cooler this day, I decided to pedal more on the way there, saving the precious battery juice for my ride home. I figured an hour would be plenty of time to get there but I didn't get out the door until 55 minutes before class, which was cutting it pretty close. Still, I was psyched to give it a try.
It's just a short two mile ride to get on an East-West bike path along the dry Rillito River bed. Once on that, I had miles of no traffic other than walkers, runners, and other cyclists. In addition, the path is lined with the burrows of round-tailed ground squirrels who are incredibly cute to watch.
About twice as big as a chipmunk, they are sandy colored and often sit up like prairie dogs. When relaxing, they sprawl out flat on the ground with their back legs splayed out, only to jump up and run into their burrows when they perceive danger. I enjoyed watching their antics as I rode, and marveled again at the few with rufous (reddish) pelts. I've never seen this color in other parts of Tucson. The color stands out, which ought to make them more susceptible to predation, but perhaps the high human activity along the path helps keep the coyotes at bay. Coyotes are not at all uncommon down in the wash but perhaps they don't make it up onto the top of the banks where the squirrels live and especially not during the day when the squirrels are active.
The squirrels scurry back and forth across the path, often dragging or carrying a mesquite bean in their mouths. This high protein bean is a great food source for them. Often they sit upright holding a bean in the front paws and nibble on it. (Click
here to see pictures of the cute little buggers eating mesquite beans.) I saw one yesterday with an odd-looking bean. I realized as I passed it that it was not a bean at all. It was a small lizard and the squirrel was busy eating it head first.
But, I digress. As I rode, I avoided using the electric assist except to get up a few little inclines where the path went under a major road. I didn't want to wear my legs out too much for class or the ride home. About a mile and a half before my destination, I had to get off the path and onto a major street for the rest of the way. I knew my time was running short and was irritated when my bike failed to trigger the green turn light, making me have to wait through another entire light cycle. I used the assist to make it through the huge and busy intersection more quickly and then used it sporadically the rest of the way as the road climbed a bit.
It took me longer than I wanted to find a place to lock up the bike, so by the time I got inside, I was late for class. This was not a big loss as the first 15 minutes are usually aerobics to warm up and a core workout. My muscles were certainly warmed up! I made it through class and then got some extra water for my ride home.
Wow. My legs were tired as I headed out. They had also stiffened up since I'd had no time to stretch the muscles before class and we mostly did upper body work. It was still overcast but the temperature was starting to climb. Nevertheless, I was determined to peddle as much as possible, not only out of principle but also to make sure I had enough battery power for the last incline just before home. It was slow going - my speed was about 1/3 less than what it had been on the way there. I stopped more frequently for water as well as to let my rear-end have a break from sitting so long. Every time I used the assist, I carefully watched the counter to keep track of how much I was using.
Eventually I made it to the final uphill stretch. I used the assist more liberally to make it home, especially since I was starting to feel pretty hot. When I pulled up to the door, I wasn't sure I'd be able to get off the bike. I did, though, got inside, and spent plenty of time stretching the tight muscles in my legs, shoulders, and neck. Then I ran the numbers.
The round trip ride was 22 1/2 miles long. Not only is this the farthest I've ridden in one day in ages, it was on a much heavier bike than usual. (Long bike frame + Xtracycle kit + electric assist and battery = heavy bike!) I used just under 1 amp hour for the entire trip, meaning I barely used the assist at all. For example, if I didn't pedal at all, the battery charge lasts for about 20 or 30 miles (I don't remember which). If I always rode like this particular trip, the battery charge would last for 225 miles!
It's good to know I can make it. On a sunnier and hotter day, I would have to use the assist more just to avoid getting heat exhaustion. I doubt I'll ride my bike tomorrow, but I will probably start riding it into class one of the two days each week. By the beginning of September, I hope to start riding it every time. With increased fitness, the time it takes me to get there should get a little shorter as well.
