I ran for 2 miles (slowly -- 5.2 to 5.7 mph) on the treadmill today -- longest since my tendinitis. Not a stitch of knee pain, and it felt so good I wanted to keep on going, but I forced myself to stop after 2 since I'd only done two one-mile runs since my two-week enforced break, and had knee twinges after both of those very short runs. No knee twinges yet tonight, so I think I can officially declare myself healed. I'll still be taking the recovery slowly and only building up mileage and speed over time. Very happy, tho!
