I always loved racing the mile, but my fave distance was 2 miles. Most weeks in summer in college, and winter, I would find a fast 2 mile or mile to shake off the cob webbs in mileage blocks.
If you can find a mile-3000m, find it. Keep it fun, and have a goal. Indoor season is here, and the events give you some idea of fitness.
For now, a mile race every other week and a mile relay (4x400m), would be adequate.
