Hehe.. cool stuff. You got four options:
1. Go totally direct, it will sub communicate that you are confident and got huge balls. It's an awesome attraction builder. You can say "hey, i know you are in middle of jogging and it's really not expected but I had to come over here and meet [you]. My name is..?" .. sinn has got a great structure for direct game which is followed by qualification hoop.
2. Use indirect or funny direct. You could jog to them and make yourself as it was real difficult for you. "I was just jogging 1000 meters to catch you guys.. i have noticed you have synchronized steps".. this is how I stop most of my moving sets in day time & night time

it requires the ability to improvise after saying it.
3. use a funny opener by mehow/brad p/whoever that has got attraction built in
4. start doing sports at same time as they are and game her on the slow track. make her see you a lot. start with just saying "hi" to the group. after few days of saying hi and u being a familiar face you can start a conversation on various topics like sports, health, her being familiar, whatever..
s-man,
