To suggest a simple answer... at this stage in your running there is no need to get too hung up on speed v time. Don't worry about the min/mile equation. If you are running regularly (this is important) with adequate rest, and following a program with some structure you will become fitter/faster.
One long run p/wk - good. One medium run p/wk - good. One interval run p/wk - good.
Running to time/heart rate and generally doing some longer easier runs over the winter will help. Your speed endurance will improve naturally as long as you are running regularly and doing the odd interval session. Once you have a few 10k's under your belt and are struggling to knock off a few secs here or there, then you can start following a more specific programme, based on your min/mile.
Building a solid foundation over the winter, without doing too much speed work, will get you fitter and stronger (strength being important) and ready for the summer season.
Maybe do some winter 5km to build leg strength? Also would suggest trying to do more outside (especially on softer surfaces) and only use the treadmill maybe once per week.
Agree with BBH. Does really depend on the size of them. If you stick compeed on a large blister it might not drain naturally and the pressure build up can become quite painful. Compeed can work ok with smaller blisters.
I'm a popper - well drain with sterile needle and tape that is. I always find the fluid in larger blisters is what causes the discomfort, smaller ones often dissapear naturally.
