What makes runners complain again and again is that the track has many steep slopes and many curves
For runners who have participated in marathon races, the course is very important, and the course with a flat and straight switchback course is easy to achieve, while the course with many steep curves is not easy to achieve, and is relatively unpopular with runners. Kipchoge, for example, broke the 2 record that year, and one of the reasons for this was that the conditions on the track also met his requirements for a record.
We runners know that the marathon events in each city have the characteristics of each local route, and the host city will generally choose local landmarks, scenic spots, etc. as part of the route, so that the city can be used as a "business card" to promote the outside world, but some attractions may not be very friendly to the runners. For example, the route of the Xi'an Marathon in previous years included some of the major attractions that went from Yongning Gate through the Big Wild Goose Pagoda and Qujiang River to the Daming Palace. Among them, several large slopes in Qujiang are about 30 kilometers away, which can make the players complain again and again.
When a runner encounters a large slope, the uphill slope will obviously lose speed, the downhill will deliberately reduce the speed appropriately, and the speed will also be deliberately reduced when encountering a curve, otherwise it will be too useless for the knees, both of which annoy the runners. Therefore, if you are a "novice" in the marathon, or even run a marathon for the first time, it is recommended to check the course route in recent years or ask the runners who have run it in advance, especially if you go to other cities to compete, so as not to have regret when you get it. Of course, runners choose a passive route when they run a horse, and they usually choose a flat and straight route when they run without a specific training goal.
