After my 'long run' yesterday I wouldn't normally run today, but we pack up tomorrow morning so I decided it would make sense to run this morning and keep it steady.
A recovery run should be run at a lower HR, right? I've been trying to run at 135-142 recently so I needed to keep in that zone as a max. But every time I began to jog my HR zoomed up to 160+. After trying to slow down in line with my new approach, I found that the only way to get it back down was to walk - then it dropped fairly readily back to 125ish. Then a slow jog would send it shooting up again. This went on for the first two miles. Eventually I managed to keep it down while jogging slowly. And nearly 3 miles done.
