The transport and acceleration of charged particles at shocks in the inner heliosphere is discussed with particular emphasis on the connection to anomalous cosmic rays and the outer heliosphere. A synthesis of recent insights regarding the acceleration of pickup ions (both of interstellar and "inner source" origin) will be given in the context of spacecraft observations. I will focus on variations in composition of energetic nuclei associated with the passage of propagating shocks. For instance, the spatial distribution of accelerated particles at corotating interaction regions (CIRs) provides constraints on possible acceleration mechanisms and sources. It will be shown that the acceleration of pickup ions is strongly favored at the reverse shock (of the two shock-pair which bounds the CIR) over the forward shock. Moreover, recent cosmic-ray observations suggest that pickup ions from the so-called "inner source" may have a noticeable effect on the abundance of anomalous cosmic rays. I will discuss the importance of the preacceleration of these pickup ions, in the inner heliosphere, prior to their acceleration at the termination shock of the solar wind. I will also discuss the propagation of energetic nuclei associated with impulsive solar flares.
