44 yo/m. I have ran 2026 miles as of today this year. I am doing around 55 miles per week the last few months. I just did a 1.20 half marathon. I am due to race Frankfurt marathon in 3 weeks time.

Today I have just felt really tired and slow. My longest training run has been 18.5 miles a fortnight ago. What should I do in the run-up to the race?

I usually do 2 marathons a year (Boston earlier in 2.52).

Am torn between whether I need to get up to 22 miles long run or just start to taper now.
