First 70.3

Len2

I am 9 weeks away from my first 70.3 event and am starting to doubt if I can do it. I have already in training completed the swim distance in a lake in just under an hour, comfortably, I have run many half marathons, in around 2hrs 30, but the furthest I have ever cycled is 38 miles, which was in the Cotswold and took around 3 hours. I cannot decide whether to keep training and just see how it goes on the day, or if I am just too far away with the bike. Any advice would be welcome
