Got a very hilly 100k sportive end of August and want to post a descent time than the previous couple of years, improve climbing and power. Loads of hills (6) 1.5 - 2 mile long ave 4% to 8% + hard undulating roads. I am carrying some extra weight 95kg 5'10" (muscular build but typical belly fat) got plenty of base miles in and going well (feeling good) overall (just done a 100k 4,000ft sportive felt great but steady pace with a slower mate) ave speed is up this year over same lumpy hilly terrain.
Ive a simple route which can include 2 types of climb up a 1km ave 4.6% max 7.4% effort then come back down then about 500mts later up a smaller steeper affair 200mts long 14% ave max 16%. Back down and start the 1st climb again and so on
Would I be best sticking to the 1 type of climb for hill repeats or would doing both types be ok in a session.
Any advice on how best to approach both for training repeats, I have a HR monitor
