Injury to Ironman
I have been out of for the past 2 years due to a number of injury's and work is it realistic to be ready for a full ironman event in 12 months ?
Are you now injury free? If so yes ... train sensibly, don't overdo it, do your stretches and get regular physio.
To finish one yes.
To race competitively for a podium/AG Kona slot,would depend on your injuries,and whether you have any re occurrences.
the greatest barrier you have is your mind telling you that it is unobtainable.
Train smart,look for realistic goals,choose the right course and why not .
