I don’t know how to pace myself

I’ve been a recreational runner for well over a decade.

I’m training for my second marathon. It’s in 12 days . I ran one 10 years ago, but I was so young, naive, undertrained, under fueled, and finished Because of adrenaline and pure stupidity.

I trained pretty hard for this one. I am currently sick during taper but I got all my long runs in, practiced with speed on the treadmill…

But I just don’t know how to pace or push myself when I’m on the road.

I finished 30km at a conversational pace and that was 7:30km/h. I finished thinking I could go further.

When I’m on the treadmill, I can push my pace much more.

I just don’t know what I should expect for the marathon? I can jog for a long time, but I don’t want to finish with gas in the tank. I want to know I gave it all I had.

But then I’m scared of gassing out. I’m scared of injuring myself.

Maranoia has hit so hard.
