You wouldn't believe how common this story is on "DI" women's teams. I'd agree with some other posters though, talk to the coach if you haven't & see if he gives you a little more leeway. You can't do much about your teammates other than train hard, encourage them to train with you in a genuine, diplomatic manner, then kick their ass & completely ignore them if they hold this against you...something not all the uncommon on women's teams. Keep in mind that if your coach wants you running as a team on recovery & long runs to keep from turning every run into a workout while truly recovering from hard workouts, this is a realistic expectation that a lot of college kids don't get. I can't tell you what your recovery pace is, but it's likely easier than what you think it is. Now, if the team is running well over 9min/mile pace every run & you are forced to do your workouts at the same pace as your other teammates...well...
Having no idea what your situation is or more details on possible conversations you've already had with your coach, it's more likely this is the administrations fault. Many athletic departments just want female numbers to off set football or other male numbers, so they hire some baby sitter they don't have to pay squat, give that person just enough scholarship $$ to keep recreational hobby-joggers to stick around on their fitness club, & just enough of a budget to make the minimum six meets per sport required for "sport sponsorship." Athletic departments need to "sponsor" so many sports (including a minimum number of women's sports) to maintain DI status. The only question in the interview or statement in job description that matters is "how many women can you give us & how cheaply can you do it?" With programs like these, there's never an expectation of athletic success... Did you know that they get to count you & your teammates three times (for Title IX purposes) if you compete in XC, indoor & outdoor track? That's a gold mine to offset other male numbers!!!
Sucks, but that sounds like your reality. If you don't like the school itself, then transfer. If you do like the school (like, for the education you went there for), then do your best to communicate with the coach...because these things don't change quickly at a program like you describe.
