Hi everyone,
thanks a lot for your replies and support! I finally did that bloody triathlon last weekend and it was amazing. What an experience, what a feeling!
No BS issue, I started with stable sugar in the morning, had a light breakfast (banana, white yoghurt, small glass of orange juice, cup of coffee) and arrived on site approx. 2 hours before start with a BS of 8mmol.
I started the 1.5km swim by taking some sugar tablets (Dextro Energy) just before entering the water. No wetsuit as it was pretty hot. 1st doubt: will I make in a good time without it? To avoid any problems, I took a gel under my swim cap. After 750m, Australian exit, few meters run and back to the water. I was so concerned about that 1st discipline, but in the end the focus and adrenaline are so intense that I did not see the time pass.
T1:: Out of the water, running to the bike (to my surprise no dizziness). 1st big shock: I had had left my glucometer next to the bike, but with 34 degrees the engine was overheating! So it was impossible to test at that point, which was the plan. Good thing is I had tried 1 week earlier the Dexcom CGM and had that sensor on the upper abs that day
Fortunately, I was online 1 minute later on the bike. I had prepared my cycling jersey with the CGM monitor in the pocket. It was showing a good 11mmol. Slightly high, but actually perfect to tackle the 40km ride. Nothing special there, a perfectly flat track around the lake, what a moment. I felt good, had some sips of my isotonic drink every now and then and finished the bike with 10mmol. I could not believe I was already starting the run!!!
T2: I change the jersey for a sleeveless t-shirt take a pack of DextroEnergy tabs for the 10km and leave the CGM monitor at transition (felt good about running without testing for 10km). Next issue, I feel completely dry!!! I realise I had not drunk enough on the bike. After my few sips of isotonic drink I stopped drinking to avoid shooting up my BS level. My bike was full of sweet drinks and sweet powerbars, but no water! Hard lesson to take: also plan for the normal case. I always plan for the worst case scenario, having enough sweet reserves here and there. Ironically this time, I tricked myself and faced a problem I never had before.
Despite having run 2 marathons and trained with quite some running sessions I admit these 10km were the longest and hardest I had to run so far. Dehydration, heat and heavy legs after the bike and swim were really testing my motivation for the final run. Fortunately there was a water station after 4km. I walked, had 3 cups of water, 1 sponge to cool down the body and started running again for the final km. I felt better then, had to walk again for 30 seconds (I was angry at myself I could not hold 10km in a row for the 1st time) and had 3 tablets of Dextro to boost me for the end. Close to the end, I felt my CGM sensor falling of, probably because of the sweat and the belt with my race number moving up and down against it.
Gran Finale: little sprint to finish my first triathlon. The end was a bit hard but the experience was worth every second! I can only recommend it.
In the end I finished in 2h41 with a 33min swim, 1h10 ride and 52min run.
I could talk/write about those 3 hours another 10 pages, but I will leave it there
In case some of you would like try but hesitate because of the sugar, trust me, you will manage! if you can handle your sugar through regular training sessions, then this kind of distances is absolutely feasible.
Since I am bit stupid and willing to discover more, I registered this morning to the Ironman 70.3 in Mallorca next May!!! I go there as I have 2 cousins and a friend who want to do it as well. Training will be a bit more intense, but after last Sunday I will tackle this next challenge with a bit more confidence
We have to be very careful - all the time, every minute - with our sugar and plan a lot in advance, but I can confirm that for sports like triathlon this can be of advantage since it's a lot about nutrition and knowing how your body reacts.
Enough talking, back to enjoying sports and hopefully I could help/motivate some of you to try it out yourself. Any questions, feel free to ask, I'd love to help.
Thanks again for your advice guys, take care!
