Marathon on Sunday set to be windy. Any help with adjustments?

1. No need to call it a "full". It's a marathon.

2. Accept that a strong headwind will slow you down several seconds per mile. Nothing you can do about it. DO NOT try to maintain pace into a strong headwind. 7:20 pace into a headwind will be 7:00 effort.

3. Take advantage of any tailwind when applicable.

4. Draft whenever you can.

What's the terrain like? If you're running through leafy neighborhoods with lots of houses and trees, you'll be much better off than if the course is on a flat plain outside of town.

But that wind is significant enough that you'll need to throw your time goal out the window.

Terrain is about 75/25 road and crushed gravel trail. All of it relatively flat with the exception of some rollers the last 6 miles. First 7 miles or so are very open travelling east (near a beach, then a river). Then it turns south and winds up some roads until the 1/2-some sections will be very open there with surrounding farms and fields. From 13 to 20 is on a trail heading west, then turns back south for the last 8-10k.

I've never personally used the technology, but I have a friend that swears by using a Stryd power meter when conditions are windy. Apparently, it detects wind, and sends information to his watch that he uses to adjust pace/effort. I run by perceived effort, but he thinks thinks the technology is the cat's meow.

Run by Hr all day long. I assume you know your Mara pace HR? I’d run to pace until HR starts to climb then back off if over working.

I have absolutely no data to back this up, but it's my feeling that wind speed seems to be the thing that forecasters get wrong most often, especially 3 days or more out.

Don't stress too much about it. Easier said than done I realize. Wind forecasts I saw for Lonson were similar right up until the day before the race. Wind turned out to be a complete non issue for the race.

Just dial into marathon effort. Don't force the pace as someone else said. It's ok to lose time. You'll likely be a couple of minutes slower than a better weather day so forget about needing to hit perfect splits & make sure you're not forcing it into the wind. You want to feel good late & take advantage of the tailwind whenever you have it in the back half but, again, if you're running marathon effort you'll naturally be running a little faster.
