For the selection of the best athletes of the month of May 2018 the races taken into consideration are only those of Taicang that have monopolized the high level of the month
So many opportunities to make good results and in choosing the best athlete of the month, Marcia dal Mondo proceeded as follows:
Men category
In this case we have considered the following performances
| Date | Event | Venue | Distance | Athlete | Result |
| | | | | | |
| 5.5.2018 | IAAF World Race Walking Team Champioships | Taicang | 50km | ARAI Hirooki | 3:44:25 |
| 5.5.2018 | IAAF World Race Walking Team Champioships | Taicang | 50km | KATSUKI Hayato | 3:44:31 |
| 5.5.2018 | IAAF World Race Walking Team Champioships | Taicang | 50km | MARUO Satoshi | 3:44:52 |
| 7.5.2018 | Chinese Grand Prix | Taicang | 20km | ZHANG Jun | 1:21:10 |
| 6.5.2018 | IAAF World Race Walking Team Champioships | Taicang | 20km | IKEDA Koki | 1:21.13 |
| 6.5.2018 | IAAF World Race Walking Team Champioships | Taicang | 20km | WANG Kaihua | 1:21:22 |
| 6.5.2018 | IAAF World Race Walking Team Champioships | Taicang | 20km | STANO Massimo | 1:21:33 |
Using the same system last month we determined the best performance in May.
| Pos. | Athlete | Result | Score points |
| | | | |
| 1. | ARAI Hirooki | 3:44:25 | 1.196 |
| 2. | KATSUKI Hayato | 3:44:31 | 1.195 |
| 3. | MARUO Satoshi | 3:44:52 | 1.193 |
| 4. | ZHANG Jun | 1:21:10 | 1.166 |
| 5. | IKEDA Koki | 1:21.13 | 1.165 |
| 6. | WANG Kaihua | 1:21:22 | 1.161 |
| 7. | STANO Massimo | 1:21.33 | 1.158 |
This month is not a question of the athlete's name of the month, as the first three nominees have all competed in the same race and the order of arrival has also determined the score.
It is more interesting to note that in the fourth place is Zhang Jun (CHN) (very young athlete of 1998, who trains in Saluzzo with Sandro Damilano) who did not participate in the IAAF World Race Walking Team Champioships, but that the following day in the leg of the Chinese Grand Prix has recorded a time of 3" better than the winner of the Championships, Koki Ikeda (JPN). It would have been very interesting to see him compete with the others.
However, the fact that the best performance is that obtained by Hirooki Arai there is no doubt. The score he got (1.196 points) reported on 20km corresponds to a time of 1:19:47 exactly 1:23 faster than Zhang Jun (CHN) and even more (1:26) by Koki Ikeda (JPN).

Women category
In this case we have considered the following performances
| Date | | Event | Venue | Distance | Athlete | Result |
| | | | | | | |
| 5.5.2018 | | IAAF World Race Walking Team Championships | Taicang | 50km | LIANG Rui | 4:04:36 |
| 5.5.2018 | | IAAF World Race Walking Team Championships | Taicang | 50km | YIN Hang | 4:09:09 |
| 5.5.2018 | | IAAF World Race Walking Team Championships | Taicang | 50km | TALLENT Claire | 4:09:33 |
| 5.5.2018 | | IAAF World Race Walking Team Championships | Taicang | 20km | GONZALEZ Maria Guadalupe | 1:26:38 |
| 5.5.2018 | | IAAF World Race Walking Team Championships | Taicang | 20km | QIEYANG Shenjie | 1:27:06 |
| 5.5.2018 | | IAAF World Race Walking Team Championships | Taicang | 20km | YANG Jiayu | 1:27:22 |
In term of score points the results are the following:
| Pos. | Athlete | Result | Score points |
| | | | |
| 1. | LIANG Rui | 4:04:36 | 1.252 |
| 2. | YIN Hang | 4:09:09 | 1.225 |
| 3. | TALLENT Claire | 4:09:33 | 1.222 |
| 4. | GONZALEZ Maria Guadalupe | 1:26:38 | 1.197 |
| 5. | QIEYANG Shenjie | 1:27:06 | 1.189 |
| 6. | YANG Jiayu | 1:27:22 | 1.184 |
There is no doubt that the athlete of the month should be Liang Rui (CHN), both for the very high score obtained and for the fact that she also established the new world record on distance.
But now we want to analyze the problem from another point of view and begin by making a comparison in terms of score with the 20km women, noting that the score obtained the Liang Rui of 1.252 points would correspond on 20km to a performarce of 1:23:37 that would broke the world record of Liu Hong by 1:01.
At this point we did the same simulation for both Jin Han and Claire Tallent.
For all three athletes we then compared the hypothetical results corresponding to the score resulting from the result of the 50km of Taicang with their personal best and the latest results obtained on 20km.
The following table is quite self-explanatory:
| Athlete | Result in 50km | Score Points | Corresponding to 20km time (A) | Personal best in 20km | Last result in 20km (B) | Difference (A) - (B) |
| | | | | | | |
| LIANG Rui | 4:04:36 | 1.252 | 1.23:37 | 1:28:43 | 1:28:50 | -5:13 |
| YIN Hang | 4:09:09 | 1.225 | 1:25:06 | 1:31:23 | 1:31:23 | -6:17 |
| TALLENT Claire | 4:09:33 | 1.222 | 1:25:16 | 1:28:53 | 1:31:29 | -6:13 |
Since it is absolutely unthinkable that an athlete who obtains such a performance on 50km, also get on the fastest distance (20km) a time of more than 5 minutes higher than that corresponding to the score obtained on 50km, (over 6 minutes in the case of Yin Hang and Claire Tallent) we allow ourselves to reflect who is duty on the algorithm that produces the score in the 50km women.
In our opinion, at the moment it is very favorable to the athletes who complete the 50km.
