I really don't know how many calories i should have a day. Maybe someone could help?

For breakfast and lunch, i always eat the same thing.

Daily Breakdown:

AM GYM: Either a 5k run, an hour of weights, or crossfit WOD
B: 1/2c almond cashew mix
L: PB&J with banana slices and an apple)
After work, I go on a 25-25 mile ride
D: Usually a something equivalent to: a salad, 1/2 avo, a meat, & taboli, maybe a sweet tater

So yeah, I really don't know if i'm on track.

Just wondering what your thoughts are and if I am eating too many/not enough calories a day. I figure the 1/2c nuts in the morning is quite a lot

Thanks girls-- i love this forum.
