Gracias, amigos, for your support and encouragement. I'm very motivated about going for a run every day but I'm worried because it could be overtraining. Perhaps it would be wiser to tale a rest day and do another sport instead. For instance, ride on bicycle, go swimming or just walk fast. As I'm taking part in a half marathon next Sunday and I've had some pain in my left knee, I want to take it easy this week and see how I am at this half marathon at Mojácar.

PS. Dan, Reflex is a spray. I find it good when I have muscle pain.

EG, I'm glad you're losing weight as well. I'd like to lose three or four more kilos.
S, if I feel worse with my knee, I'll have to try with a knee brace. I'd love to do the half marathon in January under two hours but I should do more speed runs and more streght and abdominal workouts.
