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!
in terms of comfort etc it may be up to personal choice but a tubular shirt is considered to be a lesser quality shirt than a side seamed shirt it s cheaper for t shirt manufacturers to make which explains why tubular shirts are often less expensive you can t achieve as nice a cut with tubular shirts as with side seamed and after repeat washings tubular shirts can twist and lose their shape you couldn t do a more high end fashion y t shirt with a tubular blank but lots of people like em and there is definitely a place for them in the market
