I ' m happy I have a run today . I took 3 days off in a row , due to feeling lousy and some joint issues . I started out on my 4mile and turned it into a 6.5 mile . But I was shot at 6 and gritted my teeth , sucked up the last .5 and made it home .
According to the above context, answer the following question.
What may be a valid fact about my run today ?


It was a struggle near the end .
