Cholesterol in your diet does not elevate blood serum cholesterol levels. That was debunked a long time ago in the science although many nutritionists didn't get the memo.

Back to the OP, yes endurance athletes should be getting more protein than sedentary people. At 150lbs. I shoot for 80-100g of protein per day and eggs are a great source of protein. I eat three jumbo eggs five days per week.
