My slump is on its way out

For the past couple of weeks, I've been in a slump. I've been tired during my runs, my wakeup HR has been high, and my distance and speed have been down. I've had to take walking breaks more often, especially during the first couple of miles. However, today I only took walking breaks at my schedule half-mile points, and my pace was back to the 10:15 - 10:45 range for the whole run. I've been getting more sleep at night, and that helps my body get the rest it needs.
