New Half Dome Running Record (2:30:50 by Ryan Ghelfi)
After a near miss in 2006 and bigger miss in 2007, 19 year-old Ryan Ghelfi of Redding, CA, succeeded this year in breaking the Half Dome Trail running record. On Monday, June 16, he left Happy Isles at 6:00am, touched the summit and in a mere 2:30:50 found himself back at Happy Isles, beating the old record, set by Hari Mix, by approximately seven and a half minutes (Mix ran the trail in 2:38:21). Ryan had previously done the run in 2:40, but then was disappointed last year by his 2:48 time and came back this year determined to run harder and smarter.
Like most runners, Ryan walked the steep stairs before the top of Vernal Falls, the last bit before Nevada Falls, the sub dome and the cables. He said the hardest part of the run is keeping it together for the last thirty minutes on the uphill part. He says that "It all happens in that section… Mentally that is the hardest part so prepare for that like that is the whole race. It’s going to feel slow. And I find that it is very easy to want to give up in that section". Last year, he was on record pace at the "2 miles to go" sign, but lost a lot of time between there and the summit. This year he kept it together to reach the summit in 1:32:54, running the downhill leg in 57:56.
As with previous record holders that I know of, Ryan's run was unsupported, meaning that he carried with him whatever he was going to eat and drink on the trail. He took one liter of water, a couple of Gu packs and some electrolyte tabs. He recommends taking in about 300-400 calories if you can, but he was actually only able to down 200 calories himself. By the way, he carried his water in a Nathan running pack, saying it doesn't bounce around like others. I recently got one as well and have to say that it is the most comfortable way to carry water when running. For me, hip belts bouncing up and down give me serious stomach distress after a couple of hours (though they're great for non-impact sports like skate skiing), typical Camelbaks are too bouncy and carrying water bottles in my hands just wears me out and is not practical on rough trails. So though they're a bit hard to find, definitely look into a Nathan (I'll add some links to this when I get a chance but check out ZombieRunners.com and RunnersWarehouse.com, where I got mine).
Ryan said he thinks if someone really strong heads up there, he could get the time below 2:10 and he added
I wish everybody luck who goes for this record. It has been worth it every time for me, and I hope that I get to try and break a new record again some day soon.
He may well get his wish. Previous record holder Hari Mix said: "I guess this leaves me no choice but to take the record back."
I asked Ryan for some advice for those who might try to beat his record and said he thought a few major factors contributed to his success this year:
- "For me the big difference was going to college and running on the team [Ryan is on the Southern Oregon University track team]. In high school I was not as consistent with training and I was not being pushed by faster guys."
- "Also I did a lot of Mt Biking in the month previous to the Half Dome run. I feel that it gave me some added leg strength which makes a huge difference on this run." Though I'm a slug compared to Ryan, I have to say that I find that when I do a lot of hard skiing and get my legs strong, the steps on the Mist Trail seem way, way easier. This run requires a lot more leg power than the typical run.
- Magic shoes. "I think shoe weight makes a huge difference when you have a mile of vertical. I went from using 15 ounce shoes to using 9 ounce shoes [Innovate trail racers]. Obviously you have to give up some cushion but it is worth it."
- Being fitter and mentally tougher on the last part of that climb.
He also points out that he's not as fast as Hari Mix in more traditional collegiate races (Ryan's best time in the 10K is 32:02 compared to 28:59 for Mix). Ryan does better at longer distances and probably at rough, steep trails (personally, the steeper and rougher the trail, the more likely I am to be able to keep up with a superior runner). It's not a soft record though. Previous record holders include Hari Mix, a talented collegiate runner at Stanford and Buzz Burrell, one of the elder statesmen of trail running and sponsored runner on the La Sportive Golite running team. Still, Ryan hopes to get his personal time on Half Dome down below 2:20 in the next couple of years and, as I mentioned above, said that he sees the overall record dropping below 2:10 if some really fast runner puts his mind to it. We'll see about that!
In any case, congratulations Ryan!
Some details on Ryan's run:
- Start and end: the new sign across from the old bridge (at the gauging station in other words). This is the "official" starting point for timed runs on Half Dome.

Half Dome Trail Record
Thanks for the excellent report. And the documentation was excellent too ... with more people doing stuff like this, it's important to accurately record it.

My favorite Half Dome Trail entry from the old Yosemite records log:
9:20:00 - Steve Edwards. July 98 ( no water till he cramped up and fell down in a locked up position, then ended up helping a woman out with a twisted ankle).
Thanks for the links
Thanks for the links Buzz (and in case anyone missed it, Buzz held the record on Half Dome before Hari Mix).
BTW, the old Yosemite Records log is still up and functioning, but a bit decrepit. I'm trying to spruce it up for him, but in any case, you can still find it Speedclimbing.com.
Amazing
I was surprised at his time from the bottom of the cables to the top. I assume this includes the jaunt over to the actual apex and not just the top of the cables. My personal best is 9 minutes up the cables. Gotta get there early and go up the outside. 5 1/2 mins down. Years ago, of course.
Can't imagine what his knees go thru on the downhill. ouch.

Yup, that's the time to the very top, not just the top of the cables.
I can't say I've ever timed myself on just the cables part. But yes, these boys are fit!
Is there a specific marker or
Is there a specific marker or anything to "touch" as the summit ?
Basically the high point
There's a fairly obvious high point. I think if you tag that it's okay. In other words, you don't have to locate a specific survey marker. I'll have to ask Ryan what point he uses and that would I guess be the official one since his is the time to beat.
half dome high point
I don't know exactly where I ended. That is to say it wasnt really a specific point. I went well past the cables to where seemed like it was basically the highest point, but I don't even know where the official top is. I could see well into the valley, but really I can't say the exact spot. I guess if I do it again in the future Ill end at a more definable spot.
Well, next time I'm up there,
Well, next time I'm up there, I'll take a photo of the spot that I think of as the "top" that I'm talking about. It seems obvious enough when you're there and since the record has always fallen by five minutes or more, it hasn't changed who the record holder would be. Still better to have an "official" turnaround as records get tighter.
Which electrolyte capsules?
Which electrolyte capsules did he use, and how many?
How does he carry them?
Endurolytes?
I'm not sure which caps Ryan uses, but the main ones that runners use are either Hammer Nutrition Endurolytes or Sustain caps. I use Endurolytes and have nothing but good things to say. If you can't find them just by searching Google, let me know and I'll put up a link.
As for carrying them, you can use one of those little change purses, a film cannister or a small plastic bottle or simply a small ziploc to hold them in.
Ryan and I both do our long runs with a Nathan running pack. Compared to most packs, the Nathans bounce a lot less and they have little pockets to hold, among other things, your Endurolytes in the front. You can also put in a two-liter bladder, some food and a few other essentials, so it's enough for a full-day run unsupported.
