Warm, humid morning with temperatures in the high 60's to low 70's. Mostly cloudy with an occasional breeze. I took it real easy starting out, as my ankle and achilles tendon were quite sore. Within a couple of minutes, it didn't bother me at all. I'd had some issues with my ankle on Wednesday, but didn't have any problems at all on Thursday. After a good warmup I picked the pace up, but didn't want to push it quite as hard as yesterday. When I cross my lactate threshold (which equates to a HR of about 164), not only does my breathing get a little more labored (exhales are a little more forceful), but I find that I'm thinking only running. If I'm lost in thought about something else, it's almost always an indication that I'm below that threshold. When I go above 90 percent of my maximum HR, my muscles start sending a lot of hate mail to my brain and I usually have to repeat some mantra to block it out and keep myself going. |
