OOOOOUCH! Yikes woman... you're waaay tougher than me if you climbed back on!!! This is exactly why I gave up mtn biking... I'm too big a WUSS! LOL...

glad you're doing OK other than those scrapes, which gotta hurt like heck! I have a friend who had a road crash 2 weeks ago while drafting at 25mph... broke his fork, broke his shifter into 2 pieces, snapped the handlebars in half, and his helmet ALSO split in two when he landed... he continued the skid down the road with it strapped on and flapping wildly around...

all that being said, a helmet is REAL cheap health insurance! If you have any doubts, replace it...

I don't know a ton about the pedal system you have but when my Speedplays get difficult I spray White Lightening on them... a dry lube that is really effective for me... but then, I'm not putting my foot down in dirt at all... so not sure what lube to use for mtn biking...

hope you recover and feel much better SOON!
