On Saturday, we will be camping near a Parkrun site - which I wont be able to run at on Saturday , but will go to the site on Sunday and do the 5K by myself.
I have been doing some exercising using "ladders" - described elsewhere here-- but basically it is a means to do a lot of repetitions of an exercise of which you could normally only do a small number . It is a bit like interval training - but the time of activity between intervals increases and decreases - like going up and down a ladder.
I have discovered that this form of interval training is quite well known and used with running training, but I have never heard of it being discussed here or anywhere else - so, as I was getting just a bit bored with doing the standard 5K non-stop parkrun, I am going to do intervals for 30 minutes - starting with 2minutes run/1 minute walk x1, then 3/1x1, then 4/1x1 then 5/1x1 - and then back down the ladder to 2/1x1. The time spent going up and down the ladder once is 30 minutes exactly - if I was to do 2 sets, it would be 60 minutes.
I want to see how it feels - doing intervals of different lengths - and am wondering whether this could help me to break the 30 minute barrier for the 5K ( my PB so far is 32:25) . I have programmed Runkeeper to do these intervals.
