RE: new runner - how long should it take me to run 5k? (1) For a new runner, I think a good goal would be to average under 7 minutes per mile for a 5k. 6:59 pace x 3.1 miles = 21:39. (2) After that I'd imagine 20:00 is a nice barrier. To run 19:59 you'd need to average 6:26's. (3) 18:59 - now you're starting to get a little more serious.
OP, usually when you see the term 'fitted shirts' or 'shirts in fitted sizes', that means neck and sleeve measurements describe the shirt's size. Note that users of MFA may use the term differently..... Also note that even if you buy a shirt in fitted sizes, you still probably will have to have it tailored!
Both fit and fitted are standard as past tense and past participle of fit1: The new door fit (or fitted) the old frame perfectly. The suit had fitted (or fit) well last year. Fitted is somewhat more common than fit in the sense âto adjust, make conformâ: The tailor fitted the suit with a minimum of fuss. In the passive voice, fitted is the more common past participle: The door was fitted with a new handle.
