Hey guys, I'm an up and coming Senior and I specialize in the 800m. This year my overall periodization for peaking was extremely weird. I worked hard over the summer for XC, building up to 40mpw but ended up over-training and peaking off at an 18:47 5K (XC). Going into indoor track, my season got cancelled because of COVID and I ended up making my own EXTREMELY EASY Aerobic Base-type training plan that was based off of the McMillan Running "High School Winter Training" plan which I had purchased as a reference. I ended up building a good base, but again didn't really get into PR shape all of winter season because all I was doing was building up to very high volume and easy mileage (high volume for a person like me means reaching 40mpw), a progression tempo every week, mixed in with easy stride stuff to keep the legs spinning. I feel like this kind of messed up my PR progression as well because going into outdoor season when I actually did a normal training load, I went from a 2:18 800 at the start of the season to a 1:59 by the end. And even the drop to a 1:59 was kind of rocky because I ended up getting COVID in the middle of the season! Prior to getting COVID I built my aerobic strength and mileage while progressively adding in speed workouts because I train as a Type 2 800 runner, I used 4-week mileage cycles and used the first 8 weeks of my spring season to build mileage. The progression I followed was this: 25, 29, 35, 37, 31, 35, 37, 40 (mileage isn't even because I mainly rely on minutes) while once again progressively adding in speed stuff. At the end of these 8 weeks I was going to start to decrease mileage as a whole for the last 4 weeks of my training plan and focus solely on speed, getting more and more focused around short fast reps by the end but I was unable to do this because right as soon as my 8th week ended, I got contact traced for COVID and tested positive, having to quarantine for 2 weeks. I came back, built mileage for 4 weeks (30, 35, 37, 40) again with only on really hard aerobic strength and tempo workouts to get back into shape really quickly and did only sprint work for the last 3 weeks of my season, going from running a 2:12 before sprint training to a 1:59 800 right at the start of my 7th week. However, after this my fitness kind of derailed because I didn't have enough strength to keep on sustaining sprint training and I had to start taking time off for Cross Country again. I want to know, if I had normal conditions how much faster could I have potentially ran and what kind of periodization cycle should I use for my senior year? I feel like aerobically I was reaching 4:56ish mile shape and I want to know if building to even more mileage than my coaches prescribe to me which is 40mpw over the summer is a smart idea. My current periodization plan is to really get as strong as possible during Cross Country, during Indoor Track train completely as a 400 sprinter instead of doing that extremely light base building again to gain as much raw speed as possible, and then during outdoor track go back to training as a Type 2 800 runner by increasing mileage and use that raw speed that I built during indoor season in relation to my newfound strength to rip a fast 800, potentially something big like a sub-1:55 or 1:53.
