I did my first week4 run last night on a treadmill at the gym. What can I say it felt tough but i did it so now I know I can get to week 5. I am still curious about pace though. I do the walking at 4 miles per hour (6 km/hr) and jogging at 8.5 km/hr. At the 30 min mark i.e. 2 mins into the final warm down I had completed 3.6 km so quite a way off 5 km. even if I ran for 30 min at 8.5 km/hr which seems unbelievable at the moment I would still only cover 4.25 km in 30 mins. Do i need to wind the pace up a bit?
