Birthday Hike Suggestions

I came up with the bright idea to hike 26 miles for my 26th birthday in February. Experienced hiker, comfortable hiking in hot weather and snow. For my 25th I hiked up Strawberry peak, and that was awesome but want more of a challenge.

Anyone know of hikes roughly 26 mi round trip? I’m closest to ANF, but willing to drive a bit further if needed.
