Hello

I ran my first few 5ks last fall, and decided a 10-miler would be good motivation towards the end of my pre-wedding training. I'm currently running ~14 minute mile on race day, mainly because I'm not used to running outside. I need to get to 10 minutes if possible and plan to incorporate interval training.
Does anyone have good training regimens or programs they recommend? Am I better off running without music?
The race is in April - do you think I have enough time to train?
Thanks!
