Well, I don't know a lot of everything. Just a little of everything - jack of all trades. I like to read stuff (that "stuff" does not extend into physics textbooks). What I don't know, there's always Google, Wikipedia, or Wolfram-Alpha.

If you stand by your 45,000 Calories of expenditure (does it include thermic effect of food?), then there's probably two more things to consider before you can challenge Greg's assertion that the speed force does not exist. If the amount of Calories provided by Kid Flash's body is sufficient to account for his energy output, Greg can always handwave it :)
 * 1) At 1 hour 18 minutes to go, Wally admits he was running on fumes. He arrives at the hospital with 19 minutes to go.  Thus he was essentially using up his body for an hour, plus the physical exertion of battling with Vertigo and his henchmen.  He passed out shortly after that.  Thus we will have to compute how many Calories Wally's body contains.  I don't think they burn humans in calorimeters, but we have some figures for pork .  I think 200 Calories per kilogram of weight would be fair.
 * 2) Then we'll have to determine how much of Wally's 140 pounds is muscle. We'll have to subtract skeletal mass (13%-20% in an adult), as well as the mass of his viscera.  There's a table available at Jstor.  I guess we can use the table for 14-20 year olds, average weights.
