Road Runner and I began running at the same time - after coincidentally downloading the same "From Couch to 5K" training program. We became running "partners" even though we don't run at the same pace, and she has run much longer races than I have. This last year, I was also cross-training with a triathlon program. My goal was to do my first triathlon this past fall. It didn't happen, and I'm okay with that. I realized it was a lot harder than I thought - I haven't been swimming in a while and only have consistent access to a short pool, don't have my bike handy, and have no idea how to transition from one sport to another. I did pretty well for a good while, but eventually let it fall by the wayside while I worked on my running. Recently, I found information about indoor triathlons, where you run (I think on a treadmill - though maybe on an indoor track), ride a stationary bike and swim in the pool. Thinking this is a good way to enter the triathlon world, I have just begun training for that again. Turns out, Road Runner is doing the same! Well, she's training for a triathlon - I don't know if she is going to do an indoor one first. She just started, and she is already voicing the same concerns that I had. Who knew? I guess these problems are pretty common, which must mean there are known solutions. It will be nice to compare notes. I have a different book than she does, so maybe we can swap tips.
