To post or not to post?

For the past couple of months I've been able (thank god) to break out of my funk and get some consistent training under my belt. I've aimed to get at least 50km in a week, usually more. For the second month in a row I've managed to run more than 200kms. I should be posting that on Facebook or Twitter..hell yelling it from the rooftops, but I haven't. It's not like it hasn't taken commitment or persistence (it has) but it's that I feel like I would be rubbing it in someone else's face...namely another Facebook friend. She's gotten the running bug, which is awesome. She runs 10ks and loves to post pictures of herself running. For the past couple of months she's been posting how she's gotten to 125km in a month and how thankful she is, how great her body is for doing this, how wonderful the world is because of it (not really) blah, blah..etc.. Then it's followed up by comments about how epic her effort is, how inspiring she is for doing that, etc. It gets to be a bit much when I (enviously) read my other friends’ posts about how they just ran (yet) another 100km week. So do I post about my own accomplishments, knowing they might been seen as a slap in the Facebook face by her and a pathetic attempt to gain attention by the other friends who are mileage monsters? So, I do nothing, although I'm busting my ass and achieving mileage I'd never thought possible of myself. Is there room in social media for everyone, not just the overexcited newbies and experienced mileage masters? I don't know, so I follow other, more experienced runners' lead, and don't bother posting, because really, what's most important is that I'm proud of what I did, not the social media world. I think I hear the trails calling...;-)
