In cycling time trial, the rider must reasonably allocate the energy during the cycling process to achieve good performance. Based on the objective optimization model and sensitivity analysis, this paper firstly analyzes the dynamics of different road conditions during the race; secondly, with the shortest total cycling time as the objective function and the rider's total energy limit, lactate threshold, maximum and minimum speed of cycling as the constraints, an individual time trial objective optimization model is established and the sensitivity analysis is done for both considering the influence of wind speed and wind direction on the rider. The results showed that when the wind direction was in the range of 9-11 rad, it had the least influence on the rider and was favorable to win, and when the wind direction was 7-8 rad and 16-18 rad, it was the most unfavorable to the race result; low wind speed had less influence on the rider, and when the wind speed was greater than 6 m/s, the unfavorable influence on the rider then increased.
