Quick recovery from yesterday's run

After a good solid nights sleep, and after only 14 hours since the end of yesterday's run, my wakeup heart rate was 50 this morning. My body, of course, isn't fully recovered, but having my heart rate be low is a good sign. If I sleep well tonight I should be ready for a good run tomorrow. Normally I do a 5-mile rest run on Mondays, but if I feel strong I may do 8 miles tomorrow and do the rest run on Wednesday.
