I ran my first race (a 10K) last sunday. I didn't really train for this, I just run once a week, but some friends talked me into entering the race, and so I gave it a try. It was much fun, but it gave me very sore legs ! The day after the race I could hardly walk, and now my quads and hamstrings still hurt. Is this normal ? Do people who are correctly trained for the race also get such sore legs ? And do you have any tips to prevent this, if I decide to enter another race ? thank you for your advices.
