I love the programme and think that it is amazing but I do wonder if the title sets up false expectations.
Wk1 - run one minute 6 times. Particularly for older/chunkier people this can actually be quite hard and is beyond most true couch potatoes. Perhaps advertising that you may need to build up starting off with one or tow or three of the runs and repeat until you can do all six,
Wk 9 run 3 - again particularly the older/chunkier runners, very few will achieve 5 k. Going on my current speed I'll barely hit 3k and I know from posts on here certainly be at around 4 k is not uncommon,
