Don't put yourself down, you walk every day don't you? More than enough training to be able to RUN the FLM. If you do plan to start some running in next 10 days, don't over do it too early - best thing is to start a day or two before so your muscles remember. There's not much to be lost or gained at this stage so my advice would be to put your feet up and have fresh legs for the day. After all, you don't want to pick up any late injuries by starting to train now, save energy for the sprint finish that's what I say. The crowds will push you along. Good luck to all latecomers, and welcome!
... tee hee.
