folks looking for your knowledge i have a fitness test in February for the refereeing happy to run around a field during play but my mind dies when doing laps which is 8 (3200m) in 15 minutes can't get nearer than 18.30 have been doing 5k the last 2 weeks from the front door round the local estate 1 every 2 day started at 35 minutes now down to 31 minutes very hilly run should i stick to the 5k run or should i be in the gym doing shorter runs on the treed mill to improve my speed before going for distance getting 2 different opinions
