Hi Drew, take a look at the gallery of DSLR images from Nepal below; click on each one to access the large version and caption/credits, then right-click to save on your drive. If you want larger files for any of what you see below I can upload them to DropBox for you.
As far as the Annapurna Circuit speed record goes - I didn't carry the big camera with me but have a number of high res Nepal running images from last year; in the Langtang and Mera Peak regions rather than Annapurna and not in MHW kit unfortunately, but much better quality than the iPhone selfies I snapped during the speed record. All images below of me, by me.
Hi Chris, these are the photos I came up with - let me know if you need more/others. The last two (from Madagascar) unfortunately don't get any higher res than what you see here, didn't know if you wanted them despite their small size.
