Hi everyone. I am new to this site and would appreciate any info and advice. Next year I am doing 3 marathons in 3 days and I am totally new to this. I have started training already just short walks but at the speed they need me to be at. If, no when, I complete this it will probably be the best achievement I have ever done and I will be so proud of myself. I am planning to doing extra miles and different terrains now but any advice would be appreciated. Thank you
