I know that I can get myself in trouble for focusing on individual runs in a week instead of having a broader focus on weeks of training let alone months of training, but I was hoping that someone can help me understand the potential impact of D+T on my running. I am focusing on base building in Zone 2 keeping myself below VT1 without concerning myself about pace or distance. Regardless, I still look over my run data because I'm curious if I'm seeing any improvement.
My runs this week were all 30 minutes long. I was reviewing the data last night following my run and noticed that my paces this week were 11'53", 11'37" and then 12'09"/MI. The respective dew points+temperatures were 137, 138 and then 142 last night. Is it generally considered to be a big jump going from 137/138 to 142? I'm trying to reconcile why my pace slowed down and I'm wondering if it can be attributed to the increased D+T. At the end of the day, it doesn't really matter because my focus is keeping my heartrate below VT1 during this basebuilding period. But, I am still curious the effects of D+T.
