Another indication of overdoing it, are cravings for something sweet. I'm always craving chocolate, so that doesn't help me much. And another problem with this rule, is that there are seldomly 36 hours between my runs. I run on Sunday-, Tuesday-, Thursday-, Friday- and sometimes Saturdaymorning. That's only 24 hours at best...
However, I do think it's a good rule. Sometimes I do feel tired when I go out for my run. Last week I got a cold, and had to skip two runs, and my body was really grateful! And it thanked me by running like a race horse smelling a great carrot.
I wonder if the 36-hours rule applies to motherhood… If so, I've definitely overdone things, because 36 hours after some fanatic parenting, I'm definitely still tired!
Are you familiar with the 36-hour rule?
How much time do you allow between runs?
