Triathlon and carbs
 
Do you low-carbers use carbs just for endurance events? I've done sprint triathlons (90 minutes) for 10 years. I went low-carb last April and did tris June-August. I was miserable and low-energy last summer, but by the end of August I could tell my body had adapted so I was looking forward to this tri season.

My July event I still felt sluggish and slow. (I'm slow anyway, back of the pack-er, but I felt slow even for me.) Yesterday I decided to eat a little bread and fruit the night before, and half a bagel the day of. I enjoyed the race much more and felt better. It could be coincidence.

Just wondering how others have handled this or what your experience has been.

I have done Triathlons from Sprint to Full Ironman. Being keto adapted you should not have any problem doing a Sprint on low-carb. Your body will store enough glycogen in the liver and muscles to support that 90 minute or so demand. If I were planning to race and felt like I needed to supplement I would probably tape two gels to my bike and take one at the start of the ride and one just prior to dismount. That's 200 calories and more than enough to support a hard effort race.

Just barely cut the package open and then tape it to the bike just above the cut. You can pull the gel right off the frame and it will leave the tab on the bike. Very quick and easy and no need to figure out how to open a package up as it's open as soon as you pull it off. You can tape as many as you need to your bike doing this.

Cool idea! Thanks!

I see from your info avatar that you are from San Francisco. Any plans to race Escape from Alcatraz? That race is on my bucket list is why I ask.

Awesome for you! But no, that is too ambitious for me at the moment. I have an aversion to cold water.

I was more into tris when I started. Now I just do a few local sprints every year. I may branch out a little, but probably not that far!

It depends on your level of ketoadaptation and insulin resistance. In general, your need for glycogen will diminish over time during long endurance efforts. If you were never in ketosis before, it will take longer to be able to use fat and ketones during these hard efforts, but there is a balance between the amount of carbs you can have without kicking yourself out of ketosis--it generally increases during and after a hard effort, but not before. Read Peter Attia's latest blog entry! He addresses this very issue. YOu may need to read previous entries too to understand all of the information.
