DH and I took my sister mountain biking. There's a local loop that's about 3.5 miles long and, although single track, not terribly technical, so it was perfect for her first time out. She rode my full-squish with flat pedals, and I took my rigid SS 29er. (It's nice to be the same size and have multiple bikes!)

She did great! Sure, she walked a bunch of stuff, fell a bunch, skidded the brakes too much, and steered like a drunk But she toughed it out, never complained no matter how many times she fell, and cleared plenty of rocks and roots

I'm really proud of her!
