Easy Run, 不知道是因為天氣變冷或是一陣子沒跑，現在如果不看錶，很難去確認自己的速度，雖然說7分速跟8分速沒什麼差，但跑了1年多，一般狀況下還是只能跑個8分速，還是令人有點沮喪。Probably due to the cold temp or not running for weeks, I cannot be sure how fast I run without checking my GPS watch. Even there is no big difference between 7 and 8 mins per km. It is still frustrating for me to run at 8 mins pace after more than 1 years' training.
