Task: Question Answering
Input (English): Context: It was amusing because I doubt I will use either , but I ' m sure I can find someone to give them to . My main mistake in this race was wearing XC spikes ( obviously with the spikes not screwed in ) . I had tried them out a few times in training , and thought it would be worth the experiment . They are very hard , and substantially more minimal and lighter than the flats I normally train in , and as a result they did a number on my calf muscles over the final few miles . 
Question: How may I be feeling right now ?
Output (English): Tired.
