Thanks Mary, I've got your numbers down!
Lisa, welcome to the group! Good luck training for your first marathon!
As for what to post, if you keep track of the miles and minutes that you spend doing activities then post about them here. You can post every time you do something. At the end of your training week post your totals for me and I'll record them in our spreadsheet.
Running, walking and biking count for both miles and minutes of credit.
Aerobics, weights, any kind of cross training you can think of, count for minutes.
Races count double miles and double minutes.
Umm, I hope that's clear, but if you have any questions you can let me know.
