Hey everyone! I want to announce my intention to set a new round trip FKT for this route. I will be using support from my crew at the summit, so I will target the supported FKT, however I would like to break the unsupported FKT as well. I will make my attempt on Wednesday, May 2nd starting at the beach in between 5-6AM. I have had a great winter of training and I am very excited about going after this FKT! I will submit my trail report, photos/video, and .gpx data as soon as I can following my attempt. I look forward to any comments, input, or questions :-) I can't wait to do this route!!

Planning on attempting this route tomorrow, October 27th. Not had chance to recee the lower trail hopefully it’s not too overgrown.

I wanted to let you all know I will be attempting the route on 23 MAY.  I will be using the set route that begins at the beach.  Once at the top I will then head down on the road to Kahului and end at the beach there.  I will be supported for this attempt.  It should a total of 55.5 miles.  If successful I think this may be considered as a new FKT route for others to attempt.

This attempt was exciting but it did not go as expected.  The first four miles I was greeted with a torrential downpour.  This was followed by getting lost, losing my phone, finding my phone, and finding the trail for an additional 75 minutes.  I traveled an extra 2 miles and by the time I made it to the summit I was spent as was my support crew.  I think the Ocean to Ocean attempt would still be a great adventure but not for me.  In the end, outside of an amazing time but I can only claim the slowest known time of 10:27.23.
