Newly Diagnosed Type 1 Bike Racer - High Readings

Hi, Looking for some help here.
Our son who is just 13 was diagnosed Type 1 six weeks ago. He has raced as a cyclist for the past 6 years and has reached a high level even racing nationally and lives with the hope of one day being a pro cyclist.
In the normal day to day life of school, family life he (we) have got pretty good control of his BG levels. Morning are usually around 9.5 but then generally the day is around 4.5 - 9

Our problems usually start on race days with normal readings in the morning. Although at his age races are usually just 40 mins in duration We usually reduce his insulin to 1.5 unit from a usual 2.5. He is still in his 'Honeymoon' period so is on quite small doses.
He will have breakfast of wholemeal toast or shredded wheat etc then a couple of hours later begin his warm up routine.
at this point we notice his levels are up to around 14 / 15. As his warm up continued he dropped to 10, he ate approx 1/2 an energy bar in small mouthfulls and then raced.

During the race he drank a weekened (by 50%) mix of SIS Enegry drink. The good news here is he finished a very respectible 4th from a strong field. He tested immediatly after the race and was at 21.2, he then drank water slowly for about an hour until test ing again at 17.6 before some lunch. We gave him 3.5 units of insulin (0.5 corrective dose) and a lunch of wholemeal sandwiches with Tuna / sweetcorn, crisps,

As the afternoon went on at home things were returning to normal, as an afternoon snack he had a banana, apple and satsuma then 10 minutes later plummeted quickly to 3.6.

We have been told that these extreme highs may be caused by adrenalin, but is it something we may be doing incorrectly? We are so worried of Hypo's mid race hence the munching on an energy bar pre race plus the weak energy drink.

Also would these extreme highs be affecting his Hba1c readings?

I realise that maybe this is a bit of a specialist subject but dont know where to go for help on this. Our local diabetic team are amazing but have very little experience of Type 1's during extreme excercise and race events.
Thanks for any help.

I think it is quite common for glucose levels to rise in competition due to the adrenaline .
I personally experience hypos about 5 hours after exercise if I don't reduce the bolus insulin with the next meal; but my exercise is more gentle and non competitive so I am usually low after it.
There is a wealth of useful info at the link below. As well as the theoretical info, it's worth reading what people from different sports do. I know that I have read some accounts of people who use differing strategies for competition days.

Importantly note , tucked away at the bottom of the page is this:
Do you have problems with your diabetes and sport? If so ask your G.P. or consultant to refer you to our specialized diabetes and sport clinic at the Royal Berkshire Hospital, Redaing
(sic , I think that's supposed to be Reading!)
I don't know where in the country you are but it may be worth asking for a referral.

For motivation and maybe some useful tips in the blogs of the members, he might like to look at Team T1

Hi Phoenix
Thanks for the help so far.
I've had a look at Runsweet.com and put a couple of posts on there but its seems a bit of a dormant site which is a shame.

We've also had a lot of contact with Team Novo Nordisk. It is very inspirational what those guy's (and girls) are doing, some very talented cyclists in there, and whilst they have been supported I think tend to steer away from advising which is fair enough.

So as to dealing with our sons high reading issues we're still drawing a bit of a blank.
Thanks
Simon
