Running my first marathon on Sunday!!!! Been training for months so ready to get the run started and over with. My longest run was 19 miles in 2hr 35min. Did a test run with a half marathon about 3 weeks ago and got a PR of 1:41 so hoping the weather works with me but not looking great. Humid, cloudy, drizzly which I hate. Hoping for 3:50-4:00. I would need to hold a 8:50-9:00 min per mile which is slower than training pace so I will see how I do Sunday
My little sister has been running in marathon's for about 20 years and loves it.
She's ran in the Boston as well as a few other famous marathons. She'll be running in the one down in San Antonio this weekend.
Good luck.
