Influenza A in week 15/18 if training

Hi folks,

As the title says, I should be in peak training at the moment for my first marathon, and I'm currently bed bound. Influenza A has knocked me way harder than the last bout of covid did.

I had to pull the pin on my 34km run at 16kms last sunday, as I was feeling fevered (I should've listened to my body and not ran to begin with). My 32km run this Sunday is looking unlikely.

Any thoughts on whether I would be pushing it running a 30km+ run midway through week 16? Otherwise I'd be running my first marathon with no runs above 28kms, which really doesn't feel ideal at all.

To say I'm pissed off at the timing would be an understatement.
