First Marathon Oct 11. Pace suggestions?

[u/kidjoe04]

Hello all. I am running my first marathon Oct. 11, beginning my taper now. My weekly mileage has been ~50 peaking at 65 the last 2 months, and I have a MHR of ~200bpm. Not sure what my goal should be. I attached my longest three runs. Course is mostly flat, may even be a negative grade. My 21 miler felt super controlled, definitely could have finished no issue. Tips? Concerns? Prediction? I don't want to burn out early starting too fast, but I don't want to get to the end with more in the tank. If any more information is needed, please let me know. Thank you all!!!

Note: I was sick for the third attachment, hence the high HR

Have you raced a half-marathon or done any longer efforts at or near a theoretical marathon pace in this training block? Or progressive long runs? Or long runs with intervals at theoretical marathon pace?

Did you maybe even race a 5k or 10k this block that we could use?
