today's ride was hot and boring, and while riding i had the misfortune to begin thinking about things, a couple of bicycling items came to mind and i thought i'd present them here... maybe you can help me find an answer...

i sweat a river when i work out, and ride... due to meds, i think, mostly... i know they're responsible for a lot of my weight gain over the past several years...

i've been encouraged to drink a LOT when i workout and ride, so i've taken to carrying a 2 liter h20 pack on my back... i'm up to 20-25 miles a day, and on these 90 degree plus days, i'm using up the pack... i'd like to carry another, any suggestions?

another question i had, there's a local shop here that showed me an airless tire that look like a tire filled with air, but all you do i pop it on the rim... is anyone here using them? after reading a thread about flats, i thought maybe i should think about it...

also, has anyone figured out how to compare running and cycling? i mean, how many miles riding would it take to compare with a mile of running?

the rest of my thinking leaned to the political subjects, and i won't go in to that here

cul!

Run a mile then ride the same mile.
Then you can tell us.

Where are you riding at for 90* temps?

Hydration: Use a small backpack that can carry 2 (or more) h2o bladders to make up the capacity you want. You'll end up with 2+ drinking tubes but you could always get a 'Y' adapter and combine them into one. You could also attach some cages & waterbottles to your bike which should be good for 1 - 1.5lt of additional capacity.

Plan your rides so as to take advantage of places to top up your water enroute, which is what I do. Unless you live in the middle of the Sahara you shouldn't have too much trouble finding a source of water before going through 2lt.

Comparison of cycling and rrunning: Try a heart rate monitor. Your body will be making the same aerobic effort at the same heart rate so you could chart how far/fast you run v's cycle at any given heart rate.

When it's hot I have my 70 oz Camelbak and one or two 24 oz bottles -- one filled with Gatorade.

Comparison of cycling and running: Most folks can go faster on a bike. There may be exceptions.

To get an idea of the relative exertion involved in different modes of traveling, compare the distances of the the parts of a triathlon. I'd say that the three are roughly equal in their demands on the participants.

There is a link to an interesting article comparing the difference in calories burned between running and cycling. They say running burns 110 calories per mile no matter what speed they run, and that the calories burned cycling varies but is based on the riders speed. There are a lot of factors that go into cycling, no real way to quantify them all but if you are on flats with no real tail/head wind the article gives you a good idea.

in southern KY yesterday, it was 94 degs until a late afternoon storm dropped it some, its been above 90 several days already... and the humidity is high... right now, its 94%

i looked at the forecast a bit ago, and the forecast is high 80's - low 90's the next week...

i grew up in New Mexico, i can take the heat, but the high humidity along with it makes the air so thick it feels like i'm almost swimming thru it. i've lived in different parts of KY for many years, but have never gotten used to how damp it is, i'm better, but at first, it seemed everything was always dripping.

I ride on The Texas Gulf Coast.
We traded Hills for Humidity.

If you're sweating that much, please do be careful of losing too much salt and electrolytes. You probably already know this.

sidenote spurred on by your query about running vs. cycling
-- if you're mainly cycling as your primary form of exercise, DO make time to at least do a couple of longish walks during the week... otherwise you may be prone to atrophy in various key hip/butt muscles, which aren't involved in seated-pedaling.
experts may say different, i'm saying this has happened to me, and my solution is to just make sure to do some walking!

Two words: cross train. Cycling alone is not enough. Running/walking alone is not enough. Swimming alone is not enough. Weight training alone is not enough. Especially if you're into this for the health benefits.
