Pushing the limits

Following the hardest weeks training ever I was amazed when I got up at 6am and completed my 3k swim as per the schedule (1k warm up, 5 x 200m and 10 x 100m).  My swim times were a few seconds off but training when you are tired is meant to push your limits.  In ironman you never practise a "mock race" so the first time you go the distance is on the day therefore you have to train tired as you approach the event.
A few months ago I would have needed several days off after that effort never mind the training that went on in the previous 6 days!  But it seems that the physical and mental conditioning that takes place when you train for an endurance event keeps you going.
My final big effort is on Sunday with another 80 - 100 mile bike ride and then I can look forward to tapering which will reduce my training time down to 6-7 hours and it will involve more short sharp efforts than long distance.
I have just returned from my sports massage which is the only think keeping my legs moving at the moment - it's amazing the muscle they have put on in the last 12 months.  I have a few niggles but they are under control.  A relaxing night is in order, I hope!
