Best advice I can offer (I am person managing type 1 also for 23 years, and a CDE) is to find a qualified health care provider in your area and seek their guidance. Usually, with exercise, I will (and also) encourage my patients to DECREASE the rapid acting meal coverage and correction by 40-50%, to test every 30 minutes when starting a new exercise regimen, and evaluate the patterns and trends, What is your TDI (total daily insulin intake)? = all your long and short acting insulin used in a day with reasonable control. Take this # and divide it into 1700, this will give you your sensitivity. EX:you are taking Lantus 30 Units per day, Humalog 10 Units/meal, eating 3 meals/day. Usually a type 1 in good control has about 50% of their TDI in basal (long acting) and 50% in Bolus (rapid acting). In this example, sensitivity to your Rapid insulin would be for every 1 unit Humalog, blood sugar would decrease by about 30 pts (28.33), and if your eating about 60 gms of carbs per meal, 1 unit would cover about 6 gms of carbs. So, if going to exercise and you eat, you could take 4 or 5 units H-log (when you would "normally" take 10 for the same 60 gram carb meal without exercise), do your exercise activity, test every 30 minutes during exercise, and see how your body is responding to the food consumed, insulin taken to cover the food consumed at meal before activity and the exercise, which increases your insulin sensitivity, decreasing the amount of insulin needed to "clear" a meal successfully without ending up too high or too low during and after activity. I am here to help, LMK if you have any questions. I am training for a half marathon at this time, and I understand the frustration at times, but also celebrate the success when things go well. Whole idea is to understand how much the food and insulin are pushing and pulling your individual glucose results, and for you to understand how to adapt them both to keep you safe and in goal.
