I went running yesterday morning! haha, On slept for 2 hours on Monday evening before working from 9pm till 5am :) And i went for a run at 5:30 to bukit timah NAture reserve! haha...I was satisfied with the timing. I took 46 mins to get there and 45 mins o come back.Gosh, time for me to come up with a longer route to run :D haha.. but yeah.. lack of sleep and tiredness caused me to declare that tuesday a resting day, so i ended up sleeping once i hit my room, at 6pm till 1 am. After 'dinner' i continued to sleep till 6am!! Cool, right? Well, Time to ge back on the train and chiong again!
