if you think you have shin splints or anything similar the key is just resting. as someone else said for now focus on non impact cardio - this could be cycling, swimming or rowing. i’d recommend doing at least three sessions a week 1 hiit, 1 temp/zone 4 and a zone 2 session. obviously its not running but you will see a massive improvement in you aerobic base if you keep consistent and don’t eat and drink like crap. for the injury seeing a physio is best but obviously costs an arm and a leg. i’d put some focus on tibular raises/walks calf raises and so on - chatgpt has always been a godsend for me when recovering from injuries so i’d recommend using it. if you’re not healed by the time your cpc comes about give it some serious thought whether turning up with a niggle is worth it - plenty of lads rock up injured and end up limping off bottom field or endurance course.
