Yes!!
I have a charity place for the London Marathon (rolled over from last year, when I did the virtual). It’s my first RL marathon - I’ve done lots of Halfs and one 20 mile event in the past
I agree about having goals. My dream is sub-4 (Half PB is 1:53, so a definite ‘stretch’ target, but as I said, I can dream). Realistic but good target is 4:30, third tier is 5 and after that it’s ‘just get round!’ I was slower in the virtual, but I wasn’t fully fit, it was cold, wet and had no sense of occasion!
I need to map out my proper training plan. At the moment, I’m running regularly (3 or 4 times a week up to about 8-10 miles for the longest) with the aim of consolidating basic fitness at Half level (by which I mean that if someone told me any day to run a Half tomorrow, I could do it in a reasonable time)
I’m also doing strength and conditioning at least once a week.
I’ve got two virtual Halfs and one RL one booked already - first next month - and will add more
When in proper training, one of the runs will be a challenge run (intervals/hills/tempo) and one will be long slow distance - aiming to cumulate with five weeks 18, 18, 20, 22, 20; then taper for 2-3 weeks. If I can get to the fitness when I did the 20 mile event at the tail end of 2019 (decent time, and could have kept going) then I’ll be happy
Agree that you need to get in to the habit of just dropping in to target marathon pace - it needs to feel comfortable and automatic
Remember to do as many of your long training runs on similar terrain to the race - so for me that’s flattish roads
I also need to lose a bit of weight! My best running weight is about half a stone lower than my ‘normal’ weight
Make sure your kit is really comfy (including in the wet) and sort your nutrition and hydration out by experimenting during training. Some gels give some people diarrhoea and that’s something to find out beforehand not on the day!!
And my final thought is not to get too hung up on the mileage of each run - some days can go badly. Think about time on feet as well. If you’d aimed your do 20miler, but ‘only’ cover 18 in say 3:30, that’s still good enough
