I did Grafman last weekend and that went well so I'm going to keep doing what I've been doing. For Grafman I had a 1 day taper.
Planning on just keeping going until about a week before and then having a week of reduced stuff as a taper. I'm doing a half marathon next weekend and I may shove 5 miles on the end of it to get it up to an 18 mile run. A few lake swims and my usual lots of cycling. Me and my son have made up a 101 mile route as "strava art", it looks like a giraffe's head and includes going past Whipsnade Zoo so I'll hopefully get that done, weather permitting.
My wife and children enjoyed doing the feed station so much last year, and I enjoyed the race so much too it's just a case of "bring it on!!"
