I've never liked the taste of any beer -- still don't.
Enjoy a good double-Bailey's though.
Never run a marathon, though I have run shorter "long" distances and a mini-tri. I've also dayhiked Whitney. Whitney seems easier to me, mostly mentally. Usually flat surface seemingly endless running provides little to distract from the rigors of the run, which makes it seem harder, whereas the myriad natural wonders and diversity of a trail such the MT or the MR make the long trek enjoyable, at least for me.
