Sorry, I wrote kCal when I meant kcal, or what we know as Calories. 23,244 Calories is still a ridiculous amount. We can fine-tune our thought experiment further with this article on Michael Phelps' caloric intake:

Additional Assumptions
 * 1) Resting metabolic rate: 6 to 12 Calories per pound per day (at 140 pounds, that would be 35 to 70 Calories per hour)
 * 2) The upper limit for a peak Olympian-level athlete is an energy expenditure of 12,000 Calories per day (clearly making Wally super-human)
 * 3) The thermic effect of food is around 300 Calories per day to digest around 2,400 Calories of food (or around 12.5% of caloric intake)
 * 4) Wally wasn't running on wet snow (he was running mostly on frozen concrete).  However, he is running into a lot of falling snow at Mach 1 - the mass of an average snowflake is 0.5 grams
 * 5) We fine-tune the distance to Cave > Boston, then Boston > Seattle.  Batman says it's 3,000 miles (4,800 kilometers) from Boston to Seattle.  I estimate the distance from Rhode Island to Boston as 114 kilometers.
 * 6) Happy Harbor is a fictitious town, so we calculate the distance from Providence to Boston.  It's 114 km on I-95.  At the speed of sound, travel time is approximately 6 minutes (335 seconds).  This fits nicely with the in-show timestamps which has Wally teleporting into the Cave at 16:06 EST, having a quick party and mission briefing, and reaching Boston after 16:26 EST.  (That's one heck of a short party).
 * 7) Wally is carrying a "heavily-insulated" shock-proof cooler on his back.   The weight of a female human heart is about 250 grams, but I'm not going to pretend I know anything about coolers except that it contains either wet or dry ice.  Let's just make a ballpark estimate of 10 kilograms for the whole thing.
 * 8) Wally's Kid-Flash gear has to be factored in.  He's wearing a PDA, a cannister with emergency rations, and body armor that can go from polar stealth, ninja stealth, and Professor Zoom colors with the touch of a button.  It's got to weigh at least 5 kilograms.
 * 9) So Wally's total weight goes from 63 kg to 78 kg.
