Brief Answer:
Could be due to myoglobinuria

Detailed Answer:
Thanks for asking on HealthcareMagic.

Intense workout may lead to increased muscle turnover which may cause myoglobin (a muscle protein) to leak into the blood and thereby in the urine. Myoglobin resembles hemoglobin that imparts the red colour to blood and hence your observations could be related to myoglobinuria (myoglobin in urine). It can often be seen in case of excessive workouts. The following link will give you an idea regarding confirmation:

If that is the case you need to consult a doctor for the evaluation if you need some specific intervention. You would get further idea about it by visiting the following link:
