The full moon was lighting up my early morning run. I have added auto alerts to tell me when I am going slower than a 10 min pace and when my heart rate is above 174. I gave the last 3/4 mile alot of effort keeping it under a 9 minute pace and got up to under a 6 min pace sprinting the last 0.1mi. For some reason my heart rate stated out high the first quarter mile but it lowered back to normal. Ended up with 3.99mi in 38:04 I gave it my all at the end and could not finish the last 0.01mi.
