The country I live in is having a major heat wave at the moment, meaning I have to get up really early in the week to exercise as it is too hot later in the day to do my usual walk home from work etc. So I have been running round the park which is 3.1km and was wondering if it is ok to do that each day or should I give myself a rest day in between runs? It takes me around 25mins to run 3kms. If I don't get that early morning run out of the way I don't get any exercise. The other alternative is Shred one day and run the next day. Thanks in advance for any advice.
