so early game when i was around level 2 I went exploring and i found a horse with white tags at a stormcloak camp so i took it and continued on my way for about a Skyrim mile and got off and ran cuz felt faster on foot...

any way now when ever i fast travel through map or carriage this horse will be waiting for me at my destination ...

so did a I aquire a free horse ??

LOL yup, looks like you did!
