I need some advice.
I'm planning to run my first 5K on the 26th of April then another one May 31st. I've never run a race before (minus high school sprints 10 years ago

) I need some help developing a decent training schedule.
I currently run 3 mile intervals (speed and inclines) 2-4 times per week and Spin 1-2 times per week. Currently I can run a 10 minute mile without much effort. My goal is not just to run the race but to place!

So I want to get my time down to a 7-8 minute mile by May 31 if not by April 26.
I tried training for a half marathon a few months ago, but I was so mentally and physically exhausted I couldn't complete the training. I definitely overtrained!!
I would love to continue Spinning during my training. So, if anyone out there can help me develop a decent training schedule while incorporating Spinning, I would be very appreciative.
