Any success with

…a reverse taper?

It’s not what I planned. It’s not what I want. I’ve gone and farked myself up physically. I was planning a normal taper at the end of this month 3 wks prior to IMWI.

Kinda bummed. Tips and ideas would be appreciated.

what do you mean? just ramping up training till race day?

sure, works wonderfully for almost all of us people who are not doing huge volumes.

Give us a bit more to work with: your training volume for the past couple weeks? the more details the better.

x2, although a 2 day taper works even better.

Tapering is difficult. There is often little to gain, but a lot to lose. If you are unsure about a taper, try a two day taper. You might like it half way your marathon. You can’t make a lot of mistakes by tapering two days. Applying a succesfull 3 week taper is way more difficult.

If you are a bit over the edge now, rest up with a few easy and short training days. Do a few sets of 30 mins to 1 hrs for a few days and all very easy pace. Then do a kind of normal training load until two days out of the event, rest up a bit and go for it. If you are too tired now I would take it easy. It would be stupid to think you can throw yourself into a deeper hole a few weeks out of race day and expect a magic taper to fix it.

Been running anywhere from 50-75mi per week according to the plan.

Last few months, been riding 1 long endurance ride (5hrs) with intervals making up the rest of my 10-12hrs total per week.

Swimming has been more interval work. ~12-15K yds per week.
