Century Nausea(6 posts)

Century NauseaRoxy

Did two centuries this month (firsts), and had to battle major nausea the last 20 miles of both.

First one, I thought maybe it was the sports drink. But ruled that out after the second one, since I only had water.

Fuel during consisted of bananas, PB, oranges, GU, Luna Bars, cookies - pretty much the normal stuff on these rides.

Any clue?

I guess I'll be packing the Tums in addition to the Advil from now on.
Maybe a fuel conditioning thingRod

I'm OK with century rides, but I've built up to them over the last two years. Now they are just like long training rides. This year I tried my first double century, and felt sick and slightly nauseous at the end. No appetite, altho I should have been starving. Only thing that felt good was a ginger ale a couple hours after finishing. Next day I was ravenous.

I think it's a process of discovering the "right" combination of hydration and fuel for you as an endurance rider. It seems like the harder I push myself, new things that hadn't bothered me at lower levels of performance suddenly become major issues. Never used chamois creme for centuries, but chaffing was a problem on my first double. I didn't finish my second endurance ride this year. Turns out I wasn't hydrated properly, even tho I thought I was taking care of it.

It seems that as I place greater demands on my body, I'm having to pay closer attention to satisfying any critical needs. Maybe you too. I'd pack the Tums, also, but pay close attention to what and when you eat and drink and how your body responds. I'm going to spend my early spring training next year testing different foods and drink mixtures on 100 mile rides in hopes of getting it right for the endurance events.

Good luck!

sounds like you're eating SAG to SAG, or packing SAG-typical food. i ride loaded down--last weekend, for a double metric:

4 cans strawberry boost plus
3 clif bars
3 power gels
2 baggies gatorade powder
2 small cans V8

carried two medium-sized water bottles and a nike 100oz hydration pack.

i've found, over the season this year, that these are the things that work for me over long rides. i didn't eat all of this garbage on the 125, but *most* of it. SAGs served to refill my water and give me little goals in the big picture...and that huge sugar cookie at mile 90 was good.

keep trying and find what works for you.

I'd suspect the cookies. If you had a big breakfast or dinner, the fat could have triggered your digestive system to start--how shall I put this--moving things along. That's happened to me before.

I like to eat sugar on long rides to help keep my glucose levels up, but I like to avoid fat.

It may also have to do with how hard you were working on the rides. Crank the heat and/or the effort up and you can start to have problems. I've seen people "boot" after just one hour (Diablo Mtn. race) - I've also done a ride where I felt like puking almost from the beginning. It also can be due to a person's own physiology. Using a hear rate monitor will give you an idea of your effort. Tums are a help, but you may want to try doing some of your own "self guided" centuries. Get together with just a couple friends and do a big loop, but take your time and enjoy yourself. It's very easy to get all charged up on a big organized ride and push yourself. Not that this is bad, but the body needs to make adjustments if 6 to 8 hour continuous efforts are going to be part of the norm. Some easy rides as well as more demanding rides will build your base. Try using Revenge R4 for supplemental needs - also GU and some kind of power bar may help. Some fuel will work for you and some will not. I typically find that a lot of the food offered at centuries doesn't work for me - I tend to "self fuel" having learned a lot of things the hard way.

You are sweating salt. Too much water or fluids without enough salt in it (Gatorade is often mentioned as not having enough salt for long rides) and your body won't absorb it fast enough. Then the fluids sit in your stomach making you bloated and dehydrated-i.e nausea.

Amazing enough puking can help. Empties out your stomach and you can start fresh. Dog probably has some insights into this also riding where and how he does.
