Hi Tut, WOW London Marathon, I bow to you! I would love to do it but not yet, have to be realistic about what I can do! I don't buy any kit online, I go to the Nike Factory outlet in Cheshire Oaks near me but I am sure some of the other girls will help.
Hi wheresmypaddle - again, girls will help with advice but heres my twopence:
Eating - I really wouldn't be able to do a run after my evening meal, I would have a banana about an hour/half hour before or a small snack and then have evening meal later on BUT if you are wanting to keep the family together, why don't you just eat half of your meal with the family and then reheat the other half after your run?
Shin splints, I would go to a specialist running shop and get them to assess your running style and they will advise you on the current running shoe. I used to get shin splints when I did longer runs and it was because my footwear wasn't right. I wear Asics trainers now, they suit me the best but you are best getting advice.
