text: kal meri friend ne mujhe bola ki usne apna first marathon complete kiya hai,soch rahi thi ki main bhi kabhi try karun, kya bolti hai?wow, that's amazing! marathon toh ek achha challenge hai, agar tu shuru karegi toh tujhe apne limits ke baare mein pata chalega, aur kaise aage badhna hai, samajh jaayegi!
