distance is a drop in the bucket; for me it's a record.
Outstanding! It wasn't that long ago for me that a 20-mile ride
was an accomplishment - I remember it well. I'm still pretty much
a novice cyclist, really; most weeks I average 100 miles or so, and
I'm comfortable with 65 miles in 4 hours on relatively level terrain.
I *did* manage to come in a solid 580th place this weekend in the
Mount Diablo Challenge (out of 1000 riders :-)).
Quoted message said:I pedaled country roads to a small Ohio town called Harpster, which
is 15 1/2 miles away. The weather was sunny and 90-degrees...a bit
hot but a beautiful day for cycling.
Some folks like heat, but you have to be *extremely* careful about
staying hydrated. You probably want to consume about 1 liter/hour
of water with electrolytes under these conditions (or perhaps more).
Dehydration can sneak up on you and really knock you down.
Quoted message said:Two miles of the trip was on gravel, a new experience for me.
In my book, that effectively adds at least a half-mile compared to
riding on pavement :-)
Quoted message said:The bike handled it well. I made it to Harpster and stopped for a ham
and cheese sandwich and a cold Pepsi at the Kwikmart. I figured I'd
burn it off on the return ride.
It's good you're thinking about fuel - more about that later.
Quoted message said:The first 15-plus miles felt good. No problem for this 244 lb. guy.
After eating I got on my bike and headed back home. I felt good the
first 10 miles heading back but then got thirsty. I stopped for some
water and, man-o-man, it was hot!
More about hydration:
So - how often were you drinking water along the way? You probably
wanted to be drinking about one 20-ounce bottle of water with
electrolytes every hour, and *doing* so before you felt thirsty.
Drink often, like 3-4oz every 10 minutes, and take advantages of
opportunities to refill. That way, even without ice, the water isn't
likely to be as hot.
When I say "water with electrolytes", that could mean sport drink,
it could mean adding electrolyte packets to your water bottle, or it
could mean sucking down gels and chasing with water; more on this later.
Quoted message said:The sun baked my water bottle. I
drank as much as I could stand and kept going. When I was about 2 miles
from home I hit a wall. I think it's called bonking out.
You probably weren't bonking the way that the term is usually used.
Bonking/hitting the wall usually means running out of carbs, this
happens when you've depleted your muscle reserves, and almost
certainly takes further than 30 miles.
I suspect you were getting dehydrated; the first thing that
happens is that your body starts to run hot, and then you
start feeling tired-out pretty quickly. Research suggests
losing like 1% of your body weight in water is enough to start
running hot, and losing 2% can be enough to bring on the feelings
of exhaustion. Losing 2-3 pounds of water sounds like a lot, but
keep in mind, one 20oz water bottle is over 1 pound of water alone.
Quoted message said:I had already
cycled 29 miles in the heat, my water was hot and my energy level
plummeted. I stopped in the shade of a tree by the road and poured the
hot water from my bottle over my head. Man! It felt great. Really
cooled me down. I got back on the bike, grinded out the last few miles
and pulled into the driveway. I checked my Cateye computer and it
assured me I completed 31 miles. Four bottles of Ice Mountain water
later, I felt pretty good.
Heh. So consume that water during the ride next time and you might
not start to [censored] out as badly :-)
An outstanding accomplishment! Next thing you know, you'll be
reporting on the metric century you rode.
Now, about fueling - it's related to hydration. There's a lot of
advice and information about fueling and it can be difficult to
sort through it all. There are a few basic rules that seem to work
well for me.
- Just before and during a longer ride, you really want to fuel
on carbs. Sport drinks, Clif bars, gels, stuff that's high in
simple carbs and low in fat and protein. You want stuff that'll
make it into your gut and into your blood pretty quickly.
- You're probably capable of metabolizing about 250-350 calories
(kcal) an hour, so that's a decent intake rate to aim at - you'll
probably need it.
- Muscle reserves of usable carbs represent something like 1500-
2000 kcal, if you're eating properly in general.
- Burn rate is highly variable depending on weight, pace, incline,
wind, heat, etc., so you won't come up with an exact number for
any given ride. There are a number of calculators out there
that give a reasonable ball-park number (such as
http://www.kreuzotter.de/english/espeed.htm )
- Once you plug some numbers into an energy calculator, you'll quickly
realize that, at anything above a moderate pace, you'll burn more than
400 calories/hour while riding, more than you can replenish at the
same time. At the same time, if you're not riding at a really
strenuous pace, your muscle reserves will probably make up the
difference for at *least* 4 or 5 hours.
You can achieve both the fueling and hydration goals by (a) using
sport drinks or (b) by taking a handful of gels with you and drinking
water. I find that I prefer gels for longer rides, because that way
I can use any source of drinking water and don't have to pack a lot of
sport drink, but I prefer sport drink for shorter rides (1-2 hours)
because I don't have to mess with the gel packets (I just carry
two water bottles loaded with sport drink).
That ham and cheese sandwich probably wasn't hitting your gut until
after you were home - it just takes that much longer to digest.
During a ride, favor carb sources; before the ride, you might start
with a big bowl of cereal. My favorite pre-ride fuel lately has been
Cream of Wheat, 45-60 minutes before a ride, which provides a longer-
burning base of carbs.
Great ride!
