I have ADS, so I did not do much intensity during my 8 week base period for a (modified) Cat 1 50k plan. Once I hit the Intensity week I did my hill sprint workout (exactly as TftUA laid out). It was all good during the workout, but my Achilles killed me for the next 24 hours and I was only ready for Z2 base running (or Z1) after 48 hours.
Is there anything I could substitute in for the 8x10s hill sprints?
Since I still have ADS [AeT 157 AeT / AnT 185 (early 19 test for AnT)] I figured Z1/Z2 volume was more important to maintain the doing the hill sprints.
Starting in December of ’18 I began training for a marathon in March. I continued training for a 52k skyrace in June, 30mi OCR in Aug and soon a 30mi OCR on Sep 28.
This is more training mileage than I have done before, but I took the volume at prescribed increases. However, I get bad soreness and pain at the insertion point of my Achilles when I add speed. 12-24 hours after Z3 and Z4 intervals I can deal with, but hill sprints kill me. I see a PT weekly to make sure this does not turn to injury, but until my A race ends after Nov, we are just working to maintain. Once Nov/Dec hits will will progress the PT load.
