Summer vacation is almost upon us and I am hoping to conitnue my running plans since I am training for some sprint tri's. I typically run three times a week for 3 to 4 miles each and I am slow (10:30 pace). I am going to enter my 12 year old and my 9 year old son in some kid's runs and also some regular 5K runs for the 12 year old over the summer. Is there any advice out there for a training plan for the 12 year old? He is quite lazy and will resist, but he needs it and can do it if he tries - he just needs to know he can do it. I've searched the web and I've done the C25K (he did the 20 minute runs with me) but I am looking for any other advice. I definitely don't want him to end up injured or pushed too hard. Thanks!
