We had superhero soil conditions last night at 'cross practice. It had rained a bit, but things had mostly dried out, so the ground was soft and grippy. It felt like you could lean your bike as much as you wanted. At one point, on the off-camber turn around a big tree, I could feel clumps of dirt being thrown from the tire hitting my leg... pretty cool.
I'm still getting used to my new tires. I'm not sure if it was the tires, soil conditions, or what, but it seemed like I was starting to get the bike to rotate under me a little bit. When I was in to driving cars and karts, this feeling of rotation was one of my clues that I was starting to get the corners right. Not so much rotation that the rear tire breaks free (which usually slows you down), but enough that you can feel you're doing more than just tracking around an arc.
My legs felt pretty decent once I got going a bit (it was cold last night!). I felt like I mostly rode pretty well too, but I still am not riding quite as smoothly as I could. There were a few times on connected corners where I'd nail the first one, get the light moment in between the corners, but then decide I was going too fast for the second one and brake a little, which wrecked the smooth weight transfer. Intellectually, I'm sure that I could transition from that light moment into the next corner, really cram the tires into the ground and rip the second corner, but my body still isn't convinced yet. Just takes more practice I guess...
I've been running a bit for the past month or so. Just short easy runs to get the legs used to it a little. Except for the very first run, they've all gone fine, no pain or soreness later. So, with that preparation work done, this morning, I did my first session of hill sprints. It was cold enough that I was glad I was wearing a hat and wishing that I'd brought gloves too. The sprints didn't feel too hard while I was doing them (a benefit of the cold?), but I could feel it in my legs later this morning.
