How can I significantly improve running speed and time?

Have you spoken with your AFCO or looked on the British Army recruitment website? There are specific training programmes to get you up to standard for the Fitness Test.

I’ve applied to go in the RAF and I know the fitness tests are different but not by much, I would have to do a 1.5 mile run in around 13 minutes. I haven’t started training intensely yet however my boyfriends currently doing his basic training so I’ve got a lot of information from him. I would recommend not really worrying about time to begin with and just try to improve your cardiovascular endurance as although you only need to do a 1.2 mile run for the test during training you are likely to be doing much longer runs eg, 5-10 mile runs constantly so try and go for much longer runs or interval training and once you can run for a lot longer you can then give yourself goals to increase speed over time etc
