Har Sinai

I enjoyed the article on the historical location of Har Sinai.
The location of Har Sinai in Saudi Arabia actually answered a question I had from Shemos (3:1). The pasuk says that Moshe Rabbeinu left his father-in-law, Yisro kohen Midyan, to graze his sheep and he ended up at Har Ha’elokim Chorev. If Har Sinai is in the Sinai peninsula, how did he graze all the way from Midyan (which most maps put somewhere in the area of Saudia Arabia) to Egypt? Rather, it seems that Har Sinai was in Saudi Arabia and it wasn’t quite as big of a journey.
