1 in 7:06, then 20 min later did 8 in 1:02:43. I felt very good and energetic except for the last mile. I wasn't pushing the pace. After going around 8:20 pace uphill I started hyperventilating. Stopped for a few minutes while HR only got down to 115. I've had breathing problems before on easy runs, but this time I felt like I was suffocating. The last quarter uphill was the same. I went slow but when I finished my lungs were extremely tight and I couldn't breathe.
later in the day I had normal energy but I got out of breath from simple tasks like standing up and going up stairs.
