DK is actually the first thing that came to mind.

I've always been intrigued by the adventure races that involve cycling, kayaking, orienteering, etc. A teammate is looking to put together an adventure race across the state of MI, maybe 200 miles or so...I think that would be a blast.

Done: St Croix 70.3 and Powerman Zofingen
To do: Ironman Wales, Ironman Lanzarote, and Challenge Iceland

Leadville 100 comes to mind

My Strava

Not sure if it counts as knarly or enjoyable, but I'll be doing Marmotte Granfondo Alpes in about 10 weeks time. Just a really tough sportive I suppose but it has me worried! It's a 174km cycle but the route includes:

• Col du Glandon (22.0km long, 5.5% avg gradient)
• Col du Télégraphe (11.5km long, 7.3% avg gradient)
• Col du Galibier (17.6km long, 7.0% avg gradient)
• Alpe d'Huez (13.0km long, 8.0% avg gradient)

RAAM

---

2x Deca-Ironman World Cup (10 Ironmans in 10 days), 2x Quintuple Ironman World Cup (5 Ironmans in 5 days), Ultraman, Ultra Marathoner, and I once did an Ironman.

A few ideas

Swim
Catalina
English Channel
Around Manhattan
Across Tahoe
Maui Channel solo

all come to mind.

Bike
RAAM


Run
Dipsea, or 2x or 4x
Some friends did some transalp run ~7 marathons in 7 days or something
Antartica marathon

lofoten island long distance triathlon. Google lofoten islands triple.

How do you even begin to train for some of these events? This is nuts.

Do any of these races have casualties?

@floathammerholdon | @partners_in_tri

yes they do

---

2x Deca-Ironman World Cup (10 Ironmans in 10 days), 2x Quintuple Ironman World Cup (5 Ironmans in 5 days), Ultraman, Ultra Marathoner, and I once did an Ironman.

HURT 100

another bike event to add is the Belgian Waffle Ride

---

--------------------------------------------
TEAM F3 Undurance

Western States 100
Pole pedal paddle
Grinduro
Trans-Tahoe relay

More exotic would be ÖTILLÖ swimrun. But that would require me making a friend who likes to both swim and run. Harder than it sounds.

Any of the Grand Circle Trail Series races were on my bucket list. This year, I did the Antelope Canyon 55K (they also have a half marathon and 50-miler) and it was breathtaking.

(not me)

Ewwwww.

Isklar Norseman.

These may not take as long as the other ones people have listed.

Fly-by-Night Duathlon. You race on the Watkins Glen NASCAR track.

American Zofingen Duathlon. I'm sure you have read the threads.

Coincidentally, I am doing their Bryce Canyon race in June.

It is great, you'll enjoy it (when it is over)

On my list is the
Öztaler Radmarathon
London Marathon (when I finally get a start place)
IM France
Comrades marathon
Challenge Roth (in 12 weeks!)

Fits the gnarly category
