Hi Donna,

I'm a long time runner that started cycling about 3 years ago. Running can seem like a lot of work early on (and it is), but once you build up some endurance you will start to look forward to your runs - just like riding! Just remember to set SMART goals (specific, measurable, achievable, realistic and timely). Start out slow - mostly walking adding in some running gradually. I noticed someone else provided you a link for that.
I noticed you didn't find any local races (or fun runs). Maybe you can google fun runs or local races for your area and see what comes up. It helps to have something to train for - just make sure to let people know because that will help hold you accountable (always works for me).
Anyway, I wish you the best and remember to enjoy the experience.
