ATHLETE STORIES

Real athletes. Real flow.

Tisti trenutek, ko kljub splošnemu nasvetu, da se na tekmah ne testira nič novega, narediš izjemo in je to odlična izbira! Fuel ima res odličen okus in me je brez občutka utrujenosti popeljal do stopničk. Test se je tokrat res izplačal!

K24 race was my first time trying Flowdurance and it look like it went pretty good. The first thing is I didn’t have any stomach probleme during the race wich is a good base. Plus I felt I was able to push during my 2h race without loosing energy. Is that having the Flow? Probably

Tale Flowdurance okus je top, predvsem mrzu pa tud navadn je kokr utekočinjen bonbon. Druga je to, da dostav točn to kar obljub – konstanten flow v službi, na trailu ali treningu. Would recommend!

Za vse nas amaterje, rekreativce kot tudi za profesionalne športnike. Ni sladko, je zelo pitno, okus, vonj in barva pa zmagajo. Kot nekakšno gorivo, da lažje premagaš vse kilometre. Jaz ga pijem tudi v službi za lažje premagovanje vseh delovnih ur. Poizkusi! Priporočam.

Več energije in moči na klancih ter na splošno boljši občutek med tekom. Flowdurance za boljši flow!

moja prva misel? just another napitek za med športom…in se je pokazala priložnost, da ga preizkusim. Prvic sem ga preizkusila po aktivnosti, saj me je čakalo delo in naslednji dan pred cca dvourno aktivnostjo. Ko sem ga vzela med aktivnostjo in delom sem bila dejansko (presenetljivo) za čas dela ful skoncentrirana in zbrana. Naslednji dan pa med aktivnostjo sploh nisem začutila oslabljenosti, “šibkosti”, kljub višji intenzivnosti. Moram priznati, da sem nad napitkom pozitivno presenečena (tudi nad okusom) in posebno v dneh, ko sem “low energy”, si ne predstavljam športati brez predhodne doze Flowdurance-a.

Flowdurance napitek me pred tekmo lažje spravi v tekmovalno stanje tako na cestnih, kot tudi off-road preizkušnjah. Beta-alanin mi da tak prijeten občutek napetosti, da grem lažje ''na polno'', a me hkrati tudi umiri, da dam lahko od sebe svoj maksimum, hkrati pa ohranim mirno glavo.

Zelo okusen in osvežujoč napitek. Nobenih želodčnih težav po zaužitju. Pravo gorivo za naporne treninge in tekme. Enostavno navdušen.

Ko sem prvič poskusil Flowdurance, nisem mogel verjeti, kako hitro se je pokazal učinek. Ni šlo samo za energijo – občutil sem jasnost misli, osredotočenost in lažje premagovanje napora. Najbolj se je poznalo pri teku navzdol: med spustom sem lažje “skeniral” trail pred sabo, noge so ostale hitre in odzivne, misli pa mirne in osredotočene. Po šestih urah teka se pogosto zgodi, da možgani začnejo misliti na neumnosti in noge težko sledijo. Tokrat pa sem bil še vedno prisoten, zbran in sposoben razmišljati jasno, medtem ko sem se premikal hitro in sproščeno. Res je bil občutek, kot da telo in um delujeta v popolnem ritmu. To ni samo napitek za vzdržljivost – je izkušnja, ki ti pusti, da resnično uživaš v vsakem trenutku na trailu.

Odkar uporabljam Flowdurance, je moj #tekvsakdan izziv lažji in bolj efektiven. Najbolj mi je všeč, da mi da energijo brez padcev, da imam boljši fokus in da se po teku hitreje regeneriram. Opazil sem tudi, da so noge manj težke in da mi uspe lažje vztrajati iz dneva v dan. Res top izdelek za vsakega, ki veliko trenira!
