Yep, its doable! Today the UPS guy delivered my Garmin cadence sensor for my bike, and now my Garmin does new tricks!
I got it all hooked up to my bike after class, and tested it out a little bit in my apartment (pedaling backwards, not around my kitchen table). Seems like it works, now I have even more numbers that should help me train just right on the bike!
Last night I went swimming for the first time in over a week, and it went fairly well. I only swam for a little over 30 minutes, but right now I just need to get in the habit of getting in the water again. Also, with my time split between swimming, biking, and running now, my energy level is a lot lower when I'm actually in the pool than it was before break. Over time, my endurance will get better, though, just gotta be patient while my body gets used to the workload.
Today was finally a rest day, and I needed it! My legs were starting to feel rather worn out the past couple days, but this day off is just what the doctor ordered. I'm still going to do a core workout in a little bit, so the day isn't a complete bust.
Following the rest day, though, is a pretty grueling weekend. Saturday I run in the morning and bike in the evening, then Sunday I'm swimming in the morning and running in the evening. Lots of busting my tail, but my carefully calibrated schedule seems like it will let me balance school and working out ump-teen times a week!
