SUB 40 10K TT, What next?

[Kyuss]

Hello Ed,

Saturdays 10k race: 43:39..
Everything felt good until hard headwind in a small hill, i was also pulling the field from the start which was not that clever. 
I started to get fever feeling after a while because of the heat. 
It was around 32-35 Celcius..

Roadrace (Asphalt)
The splits:
3:56 m/km, 174 bpm.
3:57 m/km, 181 bpm. 
3:56 m/km, 187 bpm.
4:01 m/km, 189 bpm.
4:47 Here i could see i was getting slower and could not set a new PB so i took it easy the rest of the race. 
4:22
4:58
4:40
4:22
4:35 

All in all i was not satisfied with the race, basicly came in to the finish line breathing trough my nose. 
Felt a bit disapointed that i could not give it all.

I took a roadbike ride right after the race.
65 km, 2Hours and 9 minutes, 29 kph average. 

My body needed rest yesterday so i took a day off, i dont have any race in sight at the moment. 
I'm dedicated more than ever to develop more running endurance, so i will continue running this week but im not sure if i should start a new cycle yet. 

Best regards 
Kyuss
