I've been getting faster during the past few months, and I've modified my running goals accordingly.
Reduce my comfortable LSD pace to 10:00
Reduce my recovery pace to 11:00
Reduce my tired pace to 11:30
Nine months ago, my comfortable LSD pace was 11:30, and my recovery pace was about 12:00. My tired pace 12:30 - 13:00. I'm nearing my new goals, and after I reach them, I'll level off in speed for a few months to allow my body to adjust to the new paces. During that time, I'll focus on distance to build up my endurance again. During the past six weeks since the Salt Lake Half-Marathon, I've reduced my distance while I built up my speed.
