365/92 Training a running buddy

Spring break is upon us and it has just barely started but the kids are bored already. Hubby is going to Philly for work for two days and the rest of us are just going to hang out at home this week.
 
JD is supposed to keep his track training up while on break. He is attempting to train Ruby to be his running buddy but so far she is leading him all the wrong ways. He went less than 1 mile before he just could not take the pulling and sudden stops and then he returned home. I’m not sure it is the safest thing for him to do; he can’t afford to get an injury.
