Final Fitness Test

I have'nt done much training since last Saturday.Ive been out everyday and did an hour or two cycling at night but just short spins of 20-30 mile some repeated climbs.Im down to about 80 kilos and with the new bike I am going well up the hills.
I decided to do a final fitness test this morning as Im unsure where I am.I see no need to do the power test I usually do over 4 minutes.I know where I am there and although useful is too short a test to give me an appreciation of where I stand for the 1350 mile race.I can do about 400 watts at now 80 kilos which Im happy with.However,the key is to be able to produce as high as wattage as possible aerobically over 1350 miles.Doing a 10 mile time trial is a bit too short also and I dont want to go too high intensity with only a week to the race.So I decided to do a 100 mile out and back route which I mapped out on ridewithgps on the Youghal to Dungarvan road.The aim was not to go all out but to stay aerobic for most of the ride except for the few longish climbs on the far side of Youghal and before Dungarvan. This would give me a good appreciation of what speed I can maintain over a longer distance aerobically and be a much more appropriate test considering the distance Im racing.I was also eager to do a last longish spin before the race.
I did the 100 miles in 5 hours,my average heart rate was 139 so I was riding well within my limit averaging 20 miles an hour.There was 3400 feet of climbing.Im very happy with the result and it puts me more at ease before the race although I know no matter how fit I am this race is going to be very tough.My heart rate rose to 150-160on the climbs but I wont allow that to happen during the race as it burns to much calories and glucose which I will pay for over a long distance.I will be keeping my heart rate under 145 for the whole race.This way I will burn less calories and save my leg muscles.I believe after a few hundred miles it will be difficult anyway to get my heart rate over 140bpm my legs won't be strong enough over the distance to go harder.The limiter is ones legs and not lungs.I am interested to see what my average heart rate will be over the whole race.It could be well under 130bpm. Im just continuing to rest now.Will write a last post before the race and that will be it.The Dungarvan 100 miler I did today is below which has gradient, heart rate, distance,graphs etc.throughout the whole route.Just click on view details.The great thing about the gps 705 is others can view and download my routes,follow them and compare data. This is a test I look forward to doing again in the future.
