So in about 1.5 to 2 months i will be going to the assessment centre. I am applying for the role of Infantry so need to be able to run a mile 1/2 in under 12:45 but as of today, can only run it in about 13 1/2 minutes. Is 1 to 2 months enough time to shed that extra time and what tips can people give. I have been running outside on a relatively flat road near my house with only some minor inclines and slopes. I have only been running for a couple weeks now but am unsure if its realistic to think i can get my run to under 12 minutes in 1 to 2 months. Any and all advice is welcome, thanks.
