I took out my MP3 player and a 20m piece of string with a stake at each end to the field this morning - and gave it a good go. I went under the principle that once I missed a beep twice, I was out, and got into level 8 - I still had some stamina left, but was struggling to keep up with the speed at this point. - Firstly, I have now read you are not out until you miss two bleeps by around two metres. Is this true of the AOSB method? - Is the AOSB bleep test conducted inside, and if so, is this any easier? (I was in a cow-patted, uneven field) - How big a gap in training is there between level 8 and 10? Although I am 4/5 of the way to level 10, clearly the progression through these levels is not directly proportional. Each monday I alternate between a 1.5 mile run or a bleep test, just to gauge myself - then Wednesday and Friday I do a 3 mile. I'm going to increase Friday to 4.5 mile soon. Any more tips on increasing my bleep test would be appreciated - sadly I live in Cambridgeshire, so there is not a hill in sight!
