<a href="kavval://cities/214c8b82-771d-4392-b7fd-50d00219d072" rel="noopener noreferrer" target="_blank">New York</a>, <a href="kavval://cities/8130bfa9-043f-4407-9f40-c61a6693d8d7" rel="noopener noreferrer" target="_blank">Miami</a>, <a href="kavval://cities/1fc63874-64a8-48e8-be21-f11ae39bc6e6" rel="noopener noreferrer" target="_blank">San Francisco</a>, <a href="https://en.wikipedia.org/wiki/Detroit" rel="noopener noreferrer" target="_blank">Detroit</a>, <a href="https://en.wikipedia.org/wiki/New_Orleans" rel="noopener noreferrer" target="_blank">New Orleans</a>... How many American cities live in your memory without ever having visited them? American movies and TV series are definitely to blame. Now, it's your turn to imprint your own images, maybe during a trip or a run! Let's start in what many consider the world's most prestigious city: <a href="kavval://cities/214c8b82-771d-4392-b7fd-50d00219d072" rel="noopener noreferrer" target="_blank">New York</a>. The birthplace of <a href="https://en.wikipedia.org/wiki/Woody_Allen" rel="noopener noreferrer" target="_blank">Woody Allen</a> and <a href="https://en.wikipedia.org/wiki/Martin_Scorsese" rel="noopener noreferrer" target="_blank">Martin Scorsese</a>, one of the largest metropolises in the world, it's also home to ultra famous neighborhoods like Manhattan, the Bronx, Brooklyn, Queens, Staten Island... Legendary, we told you! Further south, still on the East Coast, New Orleans offers an entirely different setting, where jazz music 🎷 is still very much alive! In this culturally and musically rich city of <a href="kavval://level1AdminAreas/ccdd5f51-7dc3-44e3-a52d-717c29ebbb13" rel="noopener noreferrer" target="_blank">Louisiana</a>, legends like <a href="https://www.youtube.com/watch?v=Tf40GPnVz-A" rel="noopener noreferrer" target="_blank">Louis Armstrong</a> and many other artists made their mark. In <a href="kavval://level1AdminAreas/73bfa5da-ebf4-4695-8bcd-a75b6bd5bf2a" rel="noopener noreferrer" target="_blank">Florida</a>, the city of <a href="kavval://cities/8130bfa9-043f-4407-9f40-c61a6693d8d7" rel="noopener noreferrer" target="_blank">Miami</a> is worth a detour, especially since Robert "Raven" Kraft awaits to run with you every day of the year on the legendary <a href="kavval://tags/seaside" rel="noopener noreferrer" target="_blank">sand</a> that lines the city! We've talked about <a href="kavval://tags/city" rel="noopener noreferrer" target="_blank">cities</a>, but the USA is also home to incredible natural territories, such as the <a href="kavval://tags/mountain" rel="noopener noreferrer" target="_blank">Rocky Mountains</a>, stretching from the United States to <a href="kavval://countries/7455f9b8-38ad-413a-88a0-7e24a2b72066" rel="noopener noreferrer" target="_blank">Canada</a>, passing through 6 American states (!). The <a href="kavval://tags/off-road" rel="noopener noreferrer" target="_blank">national parks</a> like <a href="https://en.wikipedia.org/wiki/Yellowstone_National_Park" rel="noopener noreferrer" target="_blank">Yellowstone</a>, <a href="https://en.wikipedia.org/wiki/Grand_Teton_National_Park" rel="noopener noreferrer" target="_blank">Grand Teton</a>, <a href="https://en.wikipedia.org/wiki/Rocky_Mountain_National_Park" rel="noopener noreferrer" target="_blank">Rocky Mountain</a>, <a href="https://en.wikipedia.org/wiki/Glacier_National_Park_(U.S.)" rel="noopener noreferrer" target="_blank">Glacier</a> will offer you unique <a href="kavval://tags/off-road" rel="noopener noreferrer" target="_blank">natural settings.</a> You might encounter bears 🐻 (from a distance, of course!), grizzlies, coyotes, wolves 🐺, deer 🦌, bison 🦬, and elk... In Yellowstone, situated at an average altitude of 2400 meters, the highest peak is Eagle Peak (3462 meters). We've traveled the East, crossed the country, what about the "<a href="https://en.wikipedia.org/wiki/West_Coast_hip_hop" rel="noopener noreferrer" target="_blank">West Coast</a>"? If you're more <a href="https://www.youtube.com/watch?v=0ocYSM6pC4c&amp;list=PL34Ml1p5WjCdqAyixzlK9z2rAaZXB13IW" rel="noopener noreferrer" target="_blank">Ice Cube</a> than <a href="https://www.youtube.com/watch?v=qORYO0atB6g" rel="noopener noreferrer" target="_blank">Beastie Boys</a>, then yes, California is a must-visit for you, and we get it. <a href="kavval://cities/ba734ba8-e6cc-4ae9-8bfc-187b47f95adb" rel="noopener noreferrer" target="_blank">Los Angeles</a> and Hollywood await you! <a href="kavval://cities/5735d465-5f91-4716-8794-a21b55ff4093" rel="noopener noreferrer" target="_blank">San Diego</a>, located near the border with <a href="kavval://countries/e383d9c8-efe3-4aeb-9048-98b004f4b519" rel="noopener noreferrer" target="_blank">Mexico</a>, is a very cool multi-cultural city to live in. And the climate is very cool too ☀️! Still on the West Coast and still in <a href="kavval://level1AdminAreas/1f37fea1-d6e4-4d28-82ee-e410411dbafd" rel="noopener noreferrer" target="_blank">California</a>, <a href="kavval://cities/1fc63874-64a8-48e8-be21-f11ae39bc6e6" rel="noopener noreferrer" target="_blank">San Francisco</a> is a special city, known for its cultural openness. Can't wait to drive along its famous hills? To <a href="https://www.youtube.com/watch?v=FJZ-BHBKyos" rel="noopener noreferrer" target="_blank">reenact Bullit</a> is just a step away... Not that we recommend it. Another legendary place in the States, the mirage city of <a href="kavval://cities/58e8b6b5-76d0-4f15-96c4-2435abe401ee" rel="noopener noreferrer" target="_blank">Las Vegas</a>, with its casinos, giant shopping malls in the middle of the desert... A soon-to-be bygone era? One cannot think of this great country without mentioning cowboy culture (the ones who manage cattle 🐄, not those from western movies). Head then to the great plains of <a href="kavval://level1AdminAreas/8be07a00-a925-4d88-9bb7-d4e608b7f742" rel="noopener noreferrer" target="_blank">Texas</a> or <a href="kavval://level1AdminAreas/6834ce1b-a39c-4138-a4f8-7c3e2b17e312" rel="noopener noreferrer" target="_blank">Oregon</a>! And now, how about we look at running events? Yummy 😋.Find here the calendar of races in the United States.

We start with the most prestigious race in the world, the one everyone thinks of when talking about marathons... The <a href="kavval://events/2d9a1e24-e31b-48c7-8a17-e632ea261579" rel="noopener noreferrer" target="_blank">New York Marathon</a> of course! Every year, thousands of participants cross the <a href="https://fr.wikipedia.org/wiki/Big_Apple" rel="noopener noreferrer" target="_blank">Big Apple</a> and its most famous neighborhoods. A true holy grail for the <a href="kavval://pages/30300aa8-919d-44ac-8ca6-015258ce663e" rel="noopener noreferrer" target="_blank">road runner</a>. Stay in the American dream with a little detour to Florida, in the <a href="kavval://tags/theme-parc" rel="noopener noreferrer" target="_blank">theme park</a> <a href="https://www.disneyworld.eu/" rel="noopener noreferrer" target="_blank">Disney World</a> located near <a href="kavval://cities/4bbe3779-1a54-4e31-abe7-d5e72601a22d" rel="noopener noreferrer" target="_blank">Orlando</a>. The kids are going to love the<a href="kavval://events/de3ee0c8-5cf7-4f14-8462-07910a29cf81" rel="noopener noreferrer" target="_blank"> Walt Disney World Marathon Weekend</a>! Also nice, the <a href="kavval://events/b81370a4-baa8-4d72-b682-3bfaee05d6de" rel="noopener noreferrer" target="_blank">Women Run the Cities</a> is a <a href="kavval://tags/cause" rel="noopener noreferrer" target="_blank">charity race</a> for women only, benefitting the <a href="https://www.gotrmn.org/" rel="noopener noreferrer" target="_blank">Girls on the Run</a> organization! The event is held in the city of <a href="kavval://cities/3f503734-2ed7-4b77-af73-48b17b3febca" rel="noopener noreferrer" target="_blank">Minneapolis</a> in <a href="kavval://level1AdminAreas/ef298893-6728-46dc-abeb-2ca431351d56" rel="noopener noreferrer" target="_blank">Minnesota</a>. For ultra fans, the appointment is set in <a href="kavval://level1AdminAreas/1f37fea1-d6e4-4d28-82ee-e410411dbafd" rel="noopener noreferrer" target="_blank">California</a> for the <a href="kavval://events/5ca60722-957d-4437-b67e-267b0951a548" rel="noopener noreferrer" target="_blank">Badwater Ultra-Marathon</a>. 135 kilometers through the infamous <a href="https://fr.wikipedia.org/wiki/Vall%C3%A9e_de_la_Mort" rel="noopener noreferrer" target="_blank">Death Valley</a> ☠️... Not exactly known for its coolness! The event features a road race across deserts, dunes, and mountains in the area... Beware of hallucinations. Let's stay in the ultra domain but return to <a href="kavval://tags/off-road" rel="noopener noreferrer" target="_blank">nature</a> and <a href="kavval://pages/19c6236d-b5b7-431a-87ba-e50b74dcd383" rel="noopener noreferrer" target="_blank">trail</a> with the <a href="kavval://events/121204ab-0951-4caf-9beb-d54939dfe326" rel="noopener noreferrer" target="_blank">Hardrock 100</a>.
