I have been running for 3 months now and am not sure if i am eating enough protein. I am practically a vegetarian purely because i find meat makes me feel heavy and it is pretty calorie dense. I usually eat lots of veggies and rice/pasta and watch what i eat quite carefully.

I have previously done quite a bit of strength training and that usually requires adequate amounts of protein in order to build muscle. Is running the same, or do i not need to be as concerned about protein intake as i would be during strength training? I have supplemented my protein intake in the past and am wondering if this is also a good idea now.
