Feel like a break in the middle of the working day? Have some fun playing hacky sack, which involves keeping a small bead sack off the ground with your feet, as a group. We usually reach about 20-30 hits on any given Tuesday. The AW record to beat is 102. Time: This runs for about 30-40 minutes, just enough time to get into it and get some exercise without getting too hot and bothered. Get out of the office for some fresh air. Difficulty: 1/5 although you will get hot and you do need to have coordinated foot skills - soccer players are likely to be good at this What to wear: Wear pants and sneakers. What to bring: Sunscreen if sunny. You may also want to bring lunch. Feel free to bring a favourite hacky-sack if you have one. Note: This has been running practically every Tuesday for over seven years, rain or shine.
