Took two weeks off after Mumbai Marathon (Only stretching every other day for these two weeks). After the first two weeks of rest wanted to take it slow so have been working out three days a week, every week. Even then my knee used to hurt. So for now first target is to lose weight and get some flexibility back.
Plan for now is to Walk twice a week, strength training twice a week and long easy run only once a week.
Hopefully I am able to stick to this plan.
