Hi Everyone,

I did my first 10 mile ride today and i have attached some metrics from my HRM and cadence sensor. I am looking for some advise on what i should do better since i bonked and couldnt do steep hills at all. Excuse my ignorance with biking lingo as im still learning.

1) I used smaller gear wheel (1) for downhill (2) for flat and (3) for uphill. My Bike has a 21 speed shimano shifters
2) It was around 90F this afternoon
3) I had to ride 3 to 4 steep hills and felt like i was going to passout on the last 2 since i could not do it and felt kinda funny to get down and push the bike up

My questions:
1) what could i have done better shifting gear wise to overcome this? especially hills
2) Please look at my metrics below and let me know if my cadence or speed should be tweaked
3) Is it my bike or is it just that i am a new rider

At the end of the ride i felt great mentally and physically but i just cant get over how tired i got during those hill climbs.

If this is a training related questions feel free to move this post to the right forum. Thanks!!
