It can frequently be VERY hard to get enough protein in ones diet to satify the requirements of a hard ride or workout. This is especially true for vegetairans. I do use protein powder, but that's about it.
There was a thread on this a while back -- perhaps someone will know where it is! Suffice it to say, that protein requirements for the general population are very small, and not that much greater for your typical club endurance athlete. Even at the very highest levels (e.g., TdF), where demand is highest, protein requirements are very low (i.e., ~1.5 - 2.0 grams of protein per kg body mass per day). For typical club athletes (requirements are ~1.2 - 1.8 g/kg BM if you are training intensely). for less intense periods, ~ 0.8 - 1.2 g/kg BM) would be fine.
Data from research shows that countries such as the USA, UK, Australia (i haven't seen research on other countries, but i would expect other similar types of country to be similar) has shown that the general population consume a surfiet of protein, that at least meets and often exceeds upper limits of protein intake.
With an endurance athlete who will have to eat more food to meet energy demands of the sport, they will easily meet or exceed the protein requirements.
This holds true for vegetarians as well, especially ones who are for e.g., ovo-lactose vegetarians. Even vegans can meet or exceed the protein requirements without too much bother.
On the other hand the carbohydrate requirements to fuel endurance activities are in excess of three times the protein requirements (e.g., 6 - 10 g carbohydrate per kg body mass per day) -- and this often requires athletes to supplement their diet as carbohydrates can be quite bulky.
