The early move was a pointless waste of energy if it pushed anywhere near a maximal effort, and no-one joined. In this situation ease up on the energy input and keep rolling along. If someone comes then maybe a bit more effort might pay of. but generally early moves are low chance of success.
rejoining the peloton it's not good to drop back too far, which is why I think you may have overdone the earlier effort, and didn't recover well. This cost further on in having to move forward even if getting a little shelter. The whole field was far to spaced to get any proper shelter anyway, so more energy cost.
Lessons: In the first half of the race watch and work out who is strong, what is happening and ignore solo efforts, a small group or organised peloton chase later will nearly always work. Conserve energy, otherwise you spend it and the bill arrives later! Learn to ride much closer (is this what the references to "sphere" mean?) and get decent shelter.
Remember that the business end of a race is the last 25-30% of the distance, and it's not good going into this with too much energy used if you want a result. Only domestiques are cooked by then, for very good reasons, working for a team leader. In an individual smaller race then you have to look out for yourself, so stay in the wheels, ride first 15 in the peloton, and if you have to go through to the front early, keep the turns very short and steady.
Finally, don't get over excited - nervous energy will push your body and as I said the bill is paid later, so try and stay calm, think through the race, and conserve the big effort for when it counts.
Best of luck..!
Interesting that the officials let you start with cameras, as devices not essential for racing they are a no-no here in UK and europe, especially the helmet ones which can be the cause of all kinds of problems (gfalling off, injury to others, etc.).
