So for blood there was (until gases came on the scene) two ways blood doping (infusions or reinfusions) and epo. We have evidence for each of the following events for the two types of doping. Feel free to add to this.
100m: we have evidence that Maurice Greene used epo, as did Marion Jones, Michelle Collins, Kelli White (and presumably Tim Montgomery and Dwayne Chambers).
200m: Greene and Jones again, Bruno de Barros, Michelle Collins (epo).
400m: Saudi Arabian Al-Masrahi, Brazilian Teodoro, Kenyan Joyce Zakari, Alvin Harrison, Antonio Pettigrew, Jerome Young (epo).
800m: Russian & other Eastern European women. Ramzi world champion, Ceplak, liliana popescu, Hind Dehiba, Vanja Perisic (epo). Now if Pekka Vasala was blood doping as suspected he did go 1:44. Stephanie Graf was banned for blood doping (retrospectively after she retired).
1500m/Mile: same for the 800m, Selsouli, Adil Kaouch, Turk Cakir Alptekin, Balut, Fouad Chouki, Hind Dehiba, Christina Vasiloiu, Hachlaf (epo). S. Kiplagat and Kiprop are suspected.
3000m: definitely Komen, Mourhit, older Boulami, Baday, Bekele Defar, Sergio Sanchez (epo)
3000mSC: Boulami, Blanco, Denis, Hamid Enzzine, Hachlaf, Yin Anna, Ali Kamal, Svitlana Schmidt, Russians (epo), Jager has a 5 star rating (and he is not a hotel sadly). Kuha probably (blood doping).
5k: virtually every Moroccan male Boulami, Mourhit etc, Hassan Hirt, Russian women, Kisorio, Ahmed Baday, Sergio Sanchez, Bekele Defar, Susanne Pumper, Alberto Garcia, Noujani, Khalid Zoubaa (epo). Viren, Vainio & Maaninka (blood doping)
10k: Leghzaoui, Russians, Kisorio, Cathal Lombard, Helena Javornik, Amaia Piedra, Simone da Silva, Laila Traby (epo), suspicion surrounds Rupp (epo???).Viren, Vainio & Maaninka, Alberto Cova (blood doping)
1/2 Marathon: Barbi, Kisorio, Chepchumba, Antonello Petrei, di Cecco, Martin Fagan, José Rocha, Fernando Silva (epo).
Marathon: Abraham Kiprotich, Shobukhova, Ronald Rutto, Harroufi, Barbi, Bouramdame, Jeptoo, Sumgong and the woman stepping in epo puddles, Wilson Erupe, Julia Muraga, di Cecco, Shitaye Gemechu, Jeremias Saloj, Hunter-Galvin, Lisa Nemec, Eddy Hellebuyck, Kuma, Yu-Fang, (epo), Keitany is also suspected by the IAAF (epo), Cierpinski and possibly Yegorova (blood doping)
Walks: Schwazer, Kozhakhmetova, Ebrahim Rahimian, Athanasia Tsoumeleka, Song Hongjuan, Tysse, Gustafsson, Russians (epo),
Long Jump: Berrabah (epo)
We have alot more knowledge about who has (stupidly) failed epo, far less than blood doping.
