Cheri all of the above has happened to me too

1. Wheezing - happens to me all the time no matter how good a shape I am in , I have allergies and asthma, I work around it best I can with medication

2.Wedging gloves - As I get tired I lean more on my hands, as I got stronger this eased up also I have some gloves I like the fit on better than others

3. Hands going numb - if I am in a pace line trying to keep up I don't shift hand positions regularily so my hands go numb, talked to some of the experienced riders it happens to them to. Suggestion, shift hand postions regularily and as you get stronger this should ease up too

4. Back, pubic area, (with me also neck and shoulders) - I put on a shorter stem (for me 2" shorter), moved my seat foward about 1/4" and slight tilt down, less than 1/4". This also eased pain in my arms and hands as I wasn't leaning on them so much to stay balanced, the weight went back to my sit bones where it was supposed to be (I think in a previous post you mentioned you are long legged, short torsoed) - I would very seriously consider checking out your stem length and handle bar postion in relationship to your seat, I don't race but I like to tour so my handle bars are level with my seat - I even used a level to check and low and behold they were exact!

5. Feet - Do you use clipless pedals and road or mtn bike shoes?
When I was on standard pedals with clips my foot and leg were going numb after 12 miles. I saw it was how my foot was pronating, as I pedaled I was putting pressure on the inside of my foot. Switched to clipless with a wide float and a road shoe with a very stiff sole, now my foot stays in the proper position (I also try hard to keep my heels down as I pedal.) And I loosen my shoes after a bit if it is warm out - that makes a big difference in pressure

And congrats on the hill!
I say walking counts - you are still moving and if you didn't walk what then? ? ? roll back down ? ? ? keep riding it and soon you'll make it all the way !
We have one hill here that if you stop it is too steep to start up again and too narrow to go sideways to start, so walking is the only alternative unless you want to go back to the bottom and try again

Keep up the great riding and hope you can get the aches and pains solved.It took me doing longer and longer rides to fine tune my bike, in some cases the adjustments were miniscule. What didn't hurt at 10 miles hurt at 25 and what didn't hurt at 25 hurt at 50. Longest ride to date has been 65 miles and the bike felt GREAT Hurray! ! !

Keep me posted on what you try and what the results are.
Oh and as someone suggested previously only make 1 adjustment at a time so you know what works, I discovered some adjustments made everything worse (Mark your old settings before moving anything so you can put them back in the same spot if necessary)
