Very tiring run due to the heat and humidity. I've been running better lately and feeling more energetic overall, more than I have in years. Prior to feeling better recently, I was struggling with energy, fatigue, and falling performance. All of which became more prevalent this year. I was hoping a couple trips to the doctor would reveal the source, but other than a low WBC count there has been no performance connection. So I've self diagnosed myself and feel that my issue is a combination of low heart rate with mineral and salt losses through excessive sweating/dehydration. So working on a solution. |
