I know this subject has been beat to death recently but I'm just looking for
some final feedback before my 50k next week. Over the past few years I've
been looking for the best drinks / foods / gels etc. for my long distance
training and races. 3 years ago I discovered Endurox, then Accelerade, and
then this year I've tried Succeed Clip 2 and Succeed caps after seeing alot
of discussion about them here and elsewhere.
I tried the caps on my last 3 long training runs and I think they help alot,
taking them every 1-2 hours depending on conditions. I tried Clip 2 on my
last long run and it goes down nicely. For 6 hours, I took in 6 clip 2
packets and 5 accel gels, a large protein/carb bar, and about 150oz of total
fluid. The clip 2's are 37gm, and the accel gels are 25gm, so thats about
59 gm/ hour, plus the protein bar ate during a longer break.
I like the protein that accel gels/acclerade/endurox has in them, and I do
notice a difference in recovery since I've been using those products in my
daily training. The extra protein seems to make a difference. I wonder why
Clip 2 does not contain more protein - just 1gm vs. 34gm carbs. For this
reason I take along the protein bar in addition.
The Clip 2 has been touted here in r.r. for its low potassium content, which
is said to be more tolerable over many hours during long events. Also, it's
taste is not something you get tired of - its not sweet. My question about
Clip 2 - and about optimal refueling - is: given that the body can absorb
about 60gm carbs/hour, how much liquid is minimally needed to assist in that
absorption? What happens if you mix it much stronger? When it's cold out
you just don't need as much liquid - so how little can you get away with
when still consuming 60gm carb/hour?
Recovery refueling and nutrition is also something I'm very interested in.
I find Endurox is a great product for refueling right after exercise, and
I've used it for years. I just read parts of this book "The performance
Zone" which talks about the metabolic window right after exercising, and how
the muscles are very sensitive to insulin for the first hour or so after
exercise. It says that after 2 hours the muscles can begin to be
insulin-resistant, and can remain so for up to 16 hours after that.
Interesting stuff.
This jives with my experience that you should force yourself to ingest 100
to 300gm of carbs (depending on what exercise you did) right after exercise.
When I do this I feel great the next day; when I don't the legs aren't the
same. The addition of protein is said to speed the absorption of carbs
during this metabolic window, and also during exercise. The book is short
and has many references, but it came free with my order of Endurox -- hmmmm.
It reminds me of the book by Edmund Burke "Optimal Muscle Recovery", which
also touts the 4:1 carb/protein ratio. Both of these books are very well
referenced, and they make claims of extended endurance and better recovery
with the 4:1 ratio and ingesting at the right time.
I don't see any other studies rebutting that added protein is better. Also
it seems to make a difference in my experience. I gave my cousin who is a
bike racer some Accelerade for a xmas gift. He said he didn't like the
taste at first, but he noticed a difference in endurance and switched to
using it. I think I agree that the high potassium levels in Accelerade
don't make it ideal for ultras, so that's why I tried Clip 2, but I'm
totally convinced that added protein is better for recovery and added
endurance. Accel gels luckily don't have as much potassium as Accelerade
though (40mg vs. 65mg) so I'm planning to use Clip 2 and Accel gels during
my 50k, just like my last training run.
I've read in books and online about ultra training and alot of people seem
to agree that you need to eat extra protein during ultras, but I don't see
any products specifically formulated for this yet. In the one ultra I've
done so far (50m) they only had sweets at some of that aid stations, though
they had BBQ chicken at the base camp which we passed through 3 times. The
problem was I didn't feel like eating a piece of chicken until an hour after
the event. So what's the deal all you ultra runners out there? Do you eat
extra protein or not?
Also, while I'm on the subject of recovery, I will just share one other
thing - I've found that taking high doses of an antioxidant vitamin formula
(with A, C, E, zinc etc.) helps recovery a great deal after hard training
and races. I recommend this highly.
