I gonna ride my first race in three weeks time: 31Miles, 10 of them 7% uphill . Date July 28.
I have been biking often and running to enhace my resistance, however I would like to hear some advices to train better, what to eat and any other thing you consider will be useful during these days considering the following facts:
1. On weekdays I have just one hour per day (some time a little bit less) available for training.
2. From July 13th to July 20th I will be away from my bike and will have just 30 minutes per day.
3. I am not planning to win the race, just want to be part of it and finish it.

Thanks!
