Confidence - Going. . . going. . . gone?

The weather since the end of November has really been rubbish. Hence bike commuting ground to a halt and the turbo trainer and myself started a new phase in our relationship. Yes, that machine always ends up hurting me but I keep going back for more! So through Christmas and January I have been hitting some serious brick sessions and feeling strong. Confidence was up and I was looking forward to the Althorp Duathlon today (16 Feb 13). Firstly, due to the weather the event has been postponed until 2 March 13. Actually the weather is fine today but I understand that it is a water logged field that is the problem - transition in a field during Feb? I picked up a bug last Tuesday so the delay is actually not bad for me. There is no way I could race today. My issue now is that I feel like any decent shape that I was in for some early season triathlons has gone. I commuted to work on my bike yesterday and felt awful. Now I must take more rest and feel more confidence draining away. This whole scenario is so me! I have been like this so many times but always bounced back. I guess after a 2012 of no racing I am finding it hard to believe I can do what I did in 2011. I need to smash a decent turbo set out and run some fast mile efforts to get that confidence back - that won`t happen today! Maybe tomorrow?
