How many Calories?

First Yes I am crazy.

On Saturday I am running a Half Marathon and then on Sunday I have a biek ride for charity that is 45 miles. So I am a little worried about calories, so I eat a little more during the week so I have plenty to burn over the weekend or just eat my normal 1500-1800?

I'm not an expert, but I would eat normally during the week, then use good nutrition practice during the events. I've been training for first half on 11/8 and have had to add G2 gatorade and gu to my long runs (trying to build to 3hrs - yes I am that slow) to be able to finish them without being exhausted and feeling link junk. Realized that after 90 min hi heat runs in July.

good luck and let us know how you do!

When I've done a full carbo load I've notice a real difference ... however my half marathon PR I just ran on a whim without paying attention to what I was eating in advance (and I was actually carb depleted at the time). During the events try to fuel yourself as much as you possibly can (1 gel every 45 minutes or so - be sure to take with water).

For a full proper carb load you actually carb deplete (zero carb) for 3 days and then eat as much good carbs (plain brown rice, sweet potato, chicken...) as your body can digest (it's actually kinda gross). You may not want to go to that extreme, so you can just eat as much good carbs for the 2 or 3 days ahead of time as your body can take (regardless of calories).

Probably more important to your performance is to rest enough this week though. I would suggest doing no more than one or two 20 minute runs this week and save your energy for the race.

You will probably gain 2 or 3 lbs of water weight after this weekend, which will go away in a day or 2, so don't worry about that. I see it all the time when I have a hard weekend.
